Basel (/ˈbɑːzəl/ BAH-zəl; German: [ˈbaːzl̩] ), also known as Basle, is a city in northwestern Switzerland on the River Rhine (at the transition from the High to the Upper Rhine). Basel is Switzerland's third-most-populous city (after Zurich and Geneva), with 177,595 inhabitants within the city municipality limits. The official language of Basel is Swiss Standard German and the main spoken language is the local Basel German dialect.

Basel is commonly considered to be the cultural capital of Switzerland and the city is famous for its many museums, including the Kunstmuseum, which is the first collection of art accessible to the public in the world (1661) and the largest museum of art in Switzerland, the Fondation Beyeler (located in Riehen), the Museum Tinguely and the Museum of Contemporary Art, which is the first public museum of contemporary art in Europe. Forty museums are spread throughout the city-canton, making Basel one of the largest cultural centres in relation to its size and population in Europe.

The University of Basel, Switzerland's oldest university (founded in 1460), and the city's centuries-long commitment to humanism, have made Basel a safe haven at times of political unrest in other parts of Europe for such notable people as Erasmus of Rotterdam, the Holbein family, Friedrich Nietzsche, Carl Jung, and in the 20th century also Hermann Hesse and Karl Jaspers.

Basel was the seat of a Prince-Bishopric starting in the 11th century, and joined the Swiss Confederacy in 1501. The city has been a commercial hub and an important cultural centre since the Renaissance, and has emerged as a centre for the chemical and pharmaceutical industries in the 20th century. In 1897, Basel was chosen by Theodor Herzl as the location for the first World Zionist Congress, and altogether the congress was held there ten times over a time span of 50 years, more than in any other location. The city is also home to the world headquarters of the Bank for International Settlements. The name of the city is internationally known through institutions like the Basel Accords, Art Basel and FC Basel.

Basel is Switzerland's main centre for the pharmaceutical industry, hosting both Novartis and Roche.

In 2019 Basel was ranked the tenth most liveable city in the world by Mercer.

The name of Basel is first recorded as Basilia in the 3rd century (237/8), at the time referring to the Roman castle. This name is mostly interpreted as deriving from the personal name Basilius, from a toponym villa Basilia ("estate of Basilius") or similar.

Another suggestion derives it from a name Basilia attested in northern France as a development of basilica, the term for a public or church building (as in Bazeilles), but all of these names reference early church buildings of the 4th or 5th century and cannot be adduced for the 3rd-century attestation of Basilia.

By popular etymology, or simple assonance, the basilisk becomes closely associated with the city, used as heraldic supporter from 1448, represented on coins minted by the city, and frequently found in ornaments.

The Middle French form Basle was adopted into English, but this form has fallen gradually out of use although it continues to be used in some sections of British English including the BBC. Currently, the spelling Basel is most often used, to match the official German spelling. In French Basle was still in use in the 18th century, but was gradually replaced by the modern French spelling Basle. In Icelandic, the city is recorded as Buslaraborg in the 12th-century itinerary Leiðarvísir og borgarskipan.

There are traces of a settlement at the nearby Rhine knee from the early La Tène period (5th century BC). In the 2nd century BC, there was a village of the Raurici at the site of Basel-Gasfabrik (to the northwest of the Old City, and likely identical with the town of Arialbinnum that was mentioned on the Tabula Peutingeriana). The unfortified settlement was abandoned in the 1st century BC in favour of an oppidum on the site of Basel Minster, probably in reaction to the Roman invasion of Gaul.

In Roman Gaul, Augusta Raurica was established some 20 km (12 mi) from Basel as the regional administrative centre, while a castrum (fortified camp) was built on the site of the Celtic oppidum. In AD 83, the area was incorporated into the Roman province of Germania Superior. The Roman Senator Munatius Plancus is known as the traditional founder of Basel since the Renaissance. Roman control over the area deteriorated in the 3rd century, and Basel became an outpost of the Provincia Maxima Sequanorum formed by Diocletian. Basilia is first named by the Ammianus Marcellinus in his Res Gestae as part of the Roman military fortifications along the Rhine in the late 4th century.

The Germanic confederation of the Alemanni attempted to cross the Rhine several times in the 4th century, but were repelled; one such event was the Battle of Solicinium (368). However, in the great invasion of AD 406, the Alemanni appear to have crossed the Rhine a final time, conquering and then settling what is today Alsace and a large part of the Swiss Plateau.

The Duchy of Alemannia fell under Frankish rule in the 6th century. The Alemannic and Frankish settlement of Basel gradually grew around the old Roman castle in the 6th and 7th century. It appears that Basel surpassed the ancient regional capital of Augusta Raurica by the 7th century; based on the evidence of a gold tremissis (a small gold coin with the value of a third of a solidus) with the inscription Basilia fit, Basel seems to have minted its own coins in the 7th century.

Basel at this time was part of the Archdiocese of Besançon. A separate bishopric of Basel, replacing the ancient bishopric of Augusta Raurica, was established in the 8th century. Under bishop Haito (r. 806–823), the first cathedral was built on the site of the Roman castle (replaced by a Romanesque structure consecrated in 1019).

At the partition of the Carolingian Empire through the Treaty of Verdun in 843, Basel was first given to West Francia and became its German exclave. It passed to East Francia with the Treaty of Meerssen of 870. Basel was destroyed by the Magyars in 917. The rebuilt town became part of Upper Burgundy, and as such was incorporated into the Holy Roman Empire in 1032.

From the donation by Rudolph III of Burgundy of the Moutier-Grandval Abbey and all its possessions to Bishop Adalbero II of Metz in 999 until the Reformation, Basel was ruled by Prince-Bishops.

In 1019, the construction of the cathedral of Basel (known locally as the Münster) began under Henry II, Holy Roman Emperor.

In the 11th to 12th century, Basel gradually acquired the characteristics of a medieval city. The main market place is first mentioned in 1091. The first city walls were constructed around 1100 (with improvements made in the mid-13th and in the late 14th century). A city council of nobles and burghers is recorded for 1185, and the first mayor, Heinrich Steinlin of Murbach, for 1253. The first bridge across the Rhine was built in 1225 under bishop Heinrich von Thun (at the location of the modern Middle Bridge), and from this time the settlement of Kleinbasel gradually formed around the bridgehead on the far river bank. The bridge was largely funded by Basel's Jewish community who had settled there a century earlier. For many centuries to come Basel possessed the only permanent bridge over the river "between Lake Constance and the sea". The first city guild were the furriers, established in 1226. A total of about fifteen guilds were established in the course of the 13th century, reflecting the increasing economic prosperity of the city. The Crusade of 1267 set out from Basel.

Political conflicts between the bishops and the burghers began in the mid-13th century and continued throughout the 14th century. By the late 14th century, the city was for all practical purposes independent although it continued to nominally pledge fealty to the bishops. The House of Habsburg attempted to gain control over the city. This was not successful, but it caused a political split among the burghers of Basel into a pro-Habsburg faction, known as Sterner, and an anti-Habsburg faction, the Psitticher.

The Black Death reached Basel in 1348. The Jews were blamed, and an estimated 50 to 70 Jews were executed by burning on 16 January 1349 in what has become known as the Basel massacre. The Basel earthquake of 1356 destroyed much of the city along with a number of castles in the vicinity.

A riot on 26 February 1376, known as Böse Fasnacht, led to the killing of a number of men of Leopold III, Duke of Austria. This was seen as a serious breach of the peace, and the city council blamed "foreign ruffians" for this and executed twelve alleged perpetrators. Leopold nevertheless had the city placed under imperial ban, and in a treaty of 9 July, Basel was given a heavy fine and was placed under Habsburg control. To free itself from Habsburg hegemony, Basel joined the Swabian League of Cities in 1385, and many knights of the pro-Habsburg faction, along with duke Leopold himself, were killed in the Battle of Sempach the following year. A formal treaty with Habsburg was made in 1393.

Basel had gained its de facto independence from both the bishop and from the Habsburgs and was free to pursue its own policy of territorial expansion, beginning around 1400.

The unique representation of a bishops' crozier as the heraldic charge in the coat of arms of Basel first appears in the form of a gilded wooden staff in the 12th century. It is of unknown origin or significance (beyond its obvious status of bishop's crozier), but it is assumed to have represented a relic, possibly attributed to Saint Germanus of Granfelden. This staff (known as Baselstab) became a symbol representing the Basel diocese, depicted in bishops' seals of the late medieval period. It is represented in a heraldic context in the early 14th century, not yet as a heraldic charge but as a kind of heraldic achievement flanked by the heraldic shields of the bishop. The staff is also represented in the bishops's seals of the period. The use of the Baselstab in black as the coat of arms of the city was introduced in 1385. From this time, the Baselstab in red represented the bishop, and the same charge in black represented the city. The blazon of the municipal coat of arms is In Silber ein schwarzer Baselstab (Argent, a staff of Basel sable). In 1400, Basel was able to purchase the towns of Liestal, Homburg and Waldenburg with its surrounding territory.

In 1412 (or earlier), the well-known Gasthof zum Goldenen Sternen was established. Basel became the focal point of western Christendom during the 15th century Council of Basel (1431–1449), including the 1439 election of antipope Felix V. In 1459, Pope Pius II endowed the University of Basel, where such notables as Erasmus of Rotterdam and Paracelsus later taught. At the same time the new craft of printing was introduced to Basel by apprentices of Johann Gutenberg. In 1461, the land around Farnsburg became a part of Basel.

The Schwabe publishing house was founded in 1488 by Johannes Petri and is the oldest publishing house still in business. Johann Froben also operated his printing house in Basel and was notable for publishing works by Erasmus. In 1495, Basel was incorporated into the Upper Rhenish Imperial Circle; the Bishop of Basel was added to the Bench of the Ecclesiastical Princes of the Imperial Diet. In 1500 the construction of the Basel Münster was finished.

The city had remained neutral through the Swabian War of 1499 despite being plundered by soldiers on both sides. The Treaty of Basel ended the war and granted the Swiss confederates exemptions from the emperor Maximillian's taxes and jurisdictions, separating Switzerland de facto from the Holy Roman Empire.

On 9 June 1501, Basel joined the Swiss Confederation as its eleventh canton. It was the only canton that was asked to join, not the other way round. Basel had a strategic location, good relations with Strasbourg and Mulhouse, and control of the corn imports from Alsace, whereas the Swiss lands were becoming overpopulated and had few resources. A provision of the Charter accepting Basel required that in conflicts among the other cantons it was to stay neutral and offer its services for mediation.

In 1503, the new bishop Christoph von Utenheim refused to give Basel a new constitution; whereupon, to show its power, the city began to build a new city hall.

In 1529, the city became Protestant under Oecolampadius and the bishop's seat was moved to Porrentruy. The bishop's crook was however retained as the city's coat of arms. For centuries to come, a handful of wealthy families collectively referred to as the "Daig" played a pivotal role in city affairs as they gradually established themselves as a de facto city aristocracy.

The first edition of Christianae religionis institutio (Institutes of the Christian Religion – John Calvin's great exposition of Calvinist doctrine) was published at Basel in March 1536.

In 1544, Johann von Brugge, a rich Dutch Protestant refugee, was given citizenship and lived respectably until his death in 1556, then buried with honors. His body was exhumed and burnt at the stake in 1559 after it was discovered that he was the Anabaptist David Joris.

In 1543, De humani corporis fabrica, the first book on human anatomy, was published and printed in Basel by Andreas Vesalius (1514–1564).

There are indications Joachim Meyer, author of the influential 16th-century martial arts text Kunst des Fechten ("The Art of Fencing"), came from Basel. In 1661 the Amerbaschsches Kabinett, a vast collection of exotic artifacts, coins, medals and books was purchased by Basel. It was to become to the first public museum of art. Its collection became the core of the later Basel Museum of Art.

The Bernoulli family, which included important 17th- and 18th-century mathematicians such as Jakob Bernoulli, Johann Bernoulli and Daniel Bernoulli, were from Basel. The 18th-century mathematician Leonhard Euler was born in Basel and studied under Johann Bernoulli.

In 1792, the Republic of Rauracia, a revolutionary French client republic, was created. It lasted until 1793. After three years of political agitation and a short civil war in 1833 the disadvantaged countryside seceded from the Canton of Basel, forming the half canton of Basel-Landschaft. Between 1861 and 1878 the city walls were slighted.

On 3 July 1874, Switzerland's first zoo, the Zoo Basel, opened its doors in the south of the city towards Binningen.

In 1897 the first World Zionist Congress was held in Basel. Altogether the World Zionist Congress was held in Basel ten times, more than in any other city in the world.

On 16 November 1938, the psychedelic drug LSD was first synthesized by Swiss chemist Albert Hofmann at Sandoz Laboratories in Basel.

In 1967, the population of Basel voted in favor of buying three works of art by painter Pablo Picasso which were at risk of being sold and taken out of the local museum of art, due to a financial crisis on the part of the owner's family. Therefore, Basel became the first city in the world where the population of a political community democratically decided to acquire works of art for a public institution. Pablo Picasso was so moved by the gesture that he subsequently gifted the city with an additional three paintings.

Basel has often been the site of peace negotiations and other international meetings. The Treaty of Basel (1499) ended the Swabian War. Two years later Basel joined the Swiss Confederation. The Peace of Basel in 1795 between the French Republic and Prussia and Spain ended the First Coalition against France during the French Revolutionary Wars. In more recent times, the World Zionist Organization held its first congress in Basel from 29 August through 31 August 1897. Because of the Balkan Wars, the (Socialist) Second International held an extraordinary congress at Basel in 1912. In 1989, the Basel Convention was opened for signature with the aim of preventing the export of hazardous waste from wealthy to developing nations for disposal.

Basel is located in Northwestern Switzerland and is commonly considered to be the capital of that region. It is close to the point where the Swiss, French and German borders meet, and Basel also has suburbs in France and Germany. As of 2016, the Swiss Basel agglomeration was the third-largest in Switzerland, with a population of 541,000 in 74 municipalities in Switzerland (municipal count as of 2018). The metropolitan area, called the Trinational Eurodistrict of Basel (TEB), consists of 62 suburban communes including municipalities in neighboring countries, and counted 829,000 inhabitants in 2007.

Basel has an area, as of 2009, of 23.91 square kilometers (9.23 sq mi). Of this area, 0.95 km (0.37 sq mi) or 4.0% is used for agricultural purposes, while 0.88 km (0.34 sq mi) or 3.7% is forested. Of the rest of the land, 20.67 km (7.98 sq mi) or 86.4% is settled (buildings or roads), 1.45 km (0.56 sq mi) or 6.1% is either rivers or lakes.

Of the built up area, industrial buildings made up 10.2% of the total area while housing and buildings made up 40.7% and transportation infrastructure made up 24.0%. Power and water infrastructure as well as other special developed areas made up 2.7% of the area while parks, green belts and sports fields made up 8.9%. Out of the forested land, all of the forested land area is covered with heavy forests. Of the agricultural land, 2.5% is used for growing crops and 1.3% is pastures. All the water in the municipality is flowing water.

Under the Köppen system, Basel features an oceanic climate (Köppen: Cfb), although with notable continental influences due to its relatively far inland position with cool to cold, overcast winters and warm to hot, humid summers.

The city averages 118.2 days of rain or snow annually and on average receives 842 mm (33.1 in) of precipitation. The wettest month is May during which time Basel receives an average of 98 mm (3.9 in) of rain. The month with the most days of precipitation is also May, with an average of 11.7 days. The driest month of the year is February with an average of 45 mm (1.8 in) of precipitation over 8.4 days.

The city of Basel functions as the capital of the Swiss half-canton of Basel-Stadt.

The canton Basel-Stadt consists of three municipalities: Riehen, Bettingen, and the city Basel itself. The political structure and agencies of the city and the canton are identical.

The city itself has 19 quarters:

• Grossbasel (Greater Basel):

• Kleinbasel (Lesser Basel):

The city's and canton's executive, the Executive Council (Regierungsrat), consists of seven members for a mandate period of 4 years. They are elected by any inhabitant valid to vote on the same day as the parliament, but by means of a system of Majorz, and operates as a collegiate authority. The president (German: Regierungspräsident(in)) is elected as such by a public election, while the heads of the other departments are appointed by the collegiate. The current president is Beat Jans. The executive body holds its meetings in the red Town Hall (German: Rathaus) on the central Marktplatz. The building was built in 1504–14.

Basel's airport, EuroAirport Basel Mulhouse Freiburg, is set up for airfreight; heavy goods reach the city and the heart of continental Europe from the North Sea by ship along the Rhine.

Basel has Switzerland's only cargo port, through which goods pass along the navigable stretches of the Rhine and connect to ocean-going ships at the port of Rotterdam.

EuroAirport Basel Mulhouse Freiburg is operated jointly by two countries, France and Switzerland, although the airport is located completely on French soil. The airport itself is split into two architecturally independent sectors, one half serving the French side and the other half serving the Swiss side; prior to Schengen there was an immigration inspection point at the middle of the airport so that people could "emigrate" to the other side of the airport.

Basel has long held an important place as a rail hub. Three railway stations—those of the German, French and Swiss networks—lie within the city (although the Swiss (Basel SBB) and French (Bâle SNCF) stations are actually in the same complex, separated by Customs and Immigration facilities). Basel Badischer Bahnhof is on the opposite side of the city. Basel's local rail services are supplied by the Basel Regional S-Bahn. The largest goods railway complex of the country is located just outside the city, spanning the municipalities of Muttenz and Pratteln. The new highspeed ICE railway line from Karlsruhe to Basel was completed in 2008 while phase I of the TGV Rhin-Rhône line, opened in December 2011, has reduced travel time from Basel to Paris to about 3 hours.

Basel is located on the A3 motorway.

Within the city limits, five bridges connect Greater and Lesser Basel (downstream):

• Schwarzwaldbrücke (built 1972)
• Wettsteinbrücke (current structure built 1998, original bridge built 1879)
• Mittlere Rheinbrücke (current structure built 1905, original bridge built 1225 as the first bridge to cross the Rhine)
• Johanniterbrücke (built 1967)
• Dreirosenbrücke (built 2004, original bridge built 1935)

A somewhat anachronistic yet still widely used system of reaction ferry boats links the two shores. There are four ferries, each situated approximately midway between two bridges. Each is attached by a cable to a block that rides along another cable spanning the river at a height of 20 to 30 metres (66 to 98 feet). To cross the river, the ferryman orients the boat around 45° from the current so that the current pushes the boat across the river. This form of transportation is therefore completely hydraulically driven, requiring no outside energy source. Home/Aktuell – Fähri Verein Basel

Basel has an extensive public transportation network serving the city and connecting to surrounding suburbs, including a large tram network. Today, Basel has the largest tramway in terms of kilometers of rail tracks in Switzerland. Historically, only Geneva had a larger one at some point.

The green-colored local trams and buses are operated by the Basler Verkehrs-Betriebe (BVB). The yellow-colored buses and trams are operated by the Baselland Transport (BLT), and connect areas in the nearby half-canton of Baselland to central Basel. The BVB also shares commuter bus lines in cooperation with transit authorities in the neighboring Alsace region in France and Baden region in Germany. The Basel Regional S-Bahn, the commuter rail network connecting to suburbs surrounding the city, is jointly operated by SBB, SNCF and DB.

Basel is located at the meeting point of France, Germany, and Switzerland; because it sits on the Swiss national border and is beyond the Jura Mountains, many within the Swiss military reportedly believe that the city is indefensible during wartime. It has numerous road and rail crossings between Switzerland and the other two countries. With Switzerland joining the Schengen Area on 12 December 2008, immigration checks were no longer carried out at the crossings. However, Switzerland did not join the European Union Customs Union (though it did join the EU Single Market) and customs checks are still conducted at or near the crossings.

France-Switzerland (from east to west)

• Road crossings (with French road name continuation)
  • Kohlenstrasse (Avenue de Bâle, Huningue). This crossing replaces the former crossing Hüningerstrasse further east.
  • Elsässerstrasse (Avenue de Bâle, Saint-Louis)
  • Autobahn A3 (A35 autoroute, Saint-Louis), crossing Mulhouse, Colmar and Strasbourg.
  • EuroAirport Basel-Mulhouse-Freiburg – pedestrian walkway between the French and Swiss sections on Level 3 (departures) of airport.

• Railway crossing
  • Basel SBB railway station

Germany-Switzerland (clockwise, from north to south)

• Road crossings (with German road name continuation)

  • Between Basel SBB and Basel Badischer Bahnhof – Basel Badischer Bahnhof, and all other railway property and stations on the right bank of the Rhine belong to DB and are classed as German customs territory. Immigration and customs checks are conducted at the platform exit tunnel for passengers leaving trains here.

Additionally there are many footpaths and cycle tracks crossing the border between Basel and Germany.

As the biggest town in the Northwest of Switzerland numerous public and private health centres are located in Basel. Among others the Universitätsspital Basel and the Universitätskinderspital Basel. Private health centres include the Bethesda Spital and the Merian Iselin Klinik. Additionally the Swiss Tropical and Public Health Institute is located in Basel too.

Basel is at the forefront of a national vision to more than halve energy use in Switzerland by 2050. To research, develop and commercialise the technologies and techniques required for the country to become a 2000 Watt society, a number of projects have been set up since 2001 in the Basel metropolitan area. These include demonstration buildings constructed to Minergie or Passivhaus standards, electricity generation from renewable energy sources, and vehicles using natural gas, hydrogen and biogas. A building construction law was passed in 2002 also which stated that all new flat roofs must be greened leading to Basel becoming the world's leading green roof city. This was driven by an energy saving programme.

A hot dry rock geothermal energy project was cancelled in 2009 since it caused induced seismicity in Basel.

The city of Basel, located in the north west of Switzerland, is one of the most dynamic economic regions of Switzerland.

The Roche Tower, designed by Herzog & de Meuron, is 41 floors and 178 metres (584 ft) high, upon its opening in 2015 it has become the tallest building in Switzerland. Basel has also Switzerland's third tallest building (Basler Messeturm, 105 m (344 ft)) and Switzerland's tallest tower (St. Chrischona TV tower, 250 m (820 ft)).

The Swiss chemical industry operates largely from Basel, and Basel also has a large pharmaceutical industry. Novartis, Syngenta, Ciba Specialty Chemicals, Clariant, Hoffmann-La Roche, Basilea Pharmaceutica, and Actelion are headquartered there. Pharmaceuticals and specialty chemicals have become the modern focus of the city's industrial production.

In addition, Basel is a major European hub for Biotech and Biopharmaceuticals. There are plenty of small and mid-sized start-ups. The vibrant VC scene also supports this.

Banking is important to Basel:

• UBS AG maintains central offices in Basel.
• The Bank for International Settlements (BIS) is located within the city and is the central banker's bank.

According to the BIS, "The choice of Switzerland for the seat of the BIS was a compromise by those countries that established the BIS: Belgium, France, Germany, Italy, Japan, the United Kingdom and the United States. When consensus could not be reached on locating the Bank in London, Brussels or Amsterdam, the choice fell on Switzerland. An independent, neutral country, Switzerland offered the BIS less exposure to undue influence from any of the major powers. Within Switzerland, Basel was chosen largely because of its location, with excellent railway connections in all directions, especially important at a time when most international travel was by train."

Created in May 1930, the BIS is owned by its member central banks. No agent of the Swiss public authorities may enter the premises without the express consent of the bank. The bank exercises supervision and police power over its premises. The BIS enjoys immunity from criminal and administrative jurisdiction.

The Basel Committee on Banking Supervision usually meets at the BIS premises in Basel. It produces recommendations such as the Basel Accords (Basel I, Basel II and Basel III), based on consensus among its members which are central banks and banking supervisors.

• Basel also hosts the headquarters of the Global Infrastructure Basel Foundation, which is active in the field of sustainable infrastructure (financing).

Swiss International Air Lines, the national airline of Switzerland, is headquartered on the grounds of EuroAirport Basel-Mulhouse-Freiburg in Saint-Louis, Haut-Rhin, France, near Basel.

The Basel museums cover a broad and diverse spectrum of collections with a marked concentration in the fine arts. They house numerous holdings of international significance. The over three dozen institutions yield an extraordinarily high density of museums compared to other cities of similar size and draw over one million visitors annually.

Constituting an essential component of Basel culture and cultural policy, the museums are the result of closely interwoven private and public collecting activities and promotion of arts and culture going back to the 16th century. The public museum collection was first created back in 1661 and represents the oldest public collection in continuous existence in Europa. Since the late 1980s, various private collections have been made accessible to the public in new purpose-built structures that have been recognized as acclaimed examples of avant-garde museum architecture.

The city of Basel is a centre for numerous fairs and events all year round. One of the most important fairs for contemporary art worldwide is the Art Basel which was founded in 1970 by Ernst Beyeler and takes place in June each year. Baselworld, the watch and jewellery show (Uhren- und Schmuckmesse) one of the biggest fairs of its kind in Europe is held every year as well, and attracts a great number of tourists and dealers to the city. Live marketing company and fair organizer MCH Group has its head office in Basel.

The carnival of the city of Basel (Basler Fasnacht) is a major cultural event in the year. The carnival is the biggest in Switzerland and attracts large crowds every year, despite the fact that it starts at exactly four o'clock in the morning (Morgestraich) on a winter Monday. The Fasnacht asserts Basel's Protestant history by commencing the revelry five days after Ash Wednesday and continuing exactly 72 hours. Almost all study and work in the old city cease. Dozens of fife and drum clubs parade in medieval guild tradition with fantastical masks and illuminated lanterns.
