The Museum of the History of Barcelona (Catalan: Museu d'Història de Barcelona, MUHBA) is a history museum that conserves, researches, communicates and exhibits the historical heritage of the city of Barcelona, from its origins in Roman times until the present day. The museum's headquarters are located on Plaça del Rei, in the Barcelona Gothic Quarter (Barri Gòtic). It also manages several historic sites all around the city, most of them archaeological sites displaying remains of the ancient Roman city, called Barcino in Latin. Some others date to medieval times, including the Jewish quarter and the medieval royal palace called the Palau Reial Major. The rest are contemporary, among them old industrial buildings and sites related to Antoni Gaudí and the Spanish Civil War.

The museum was inaugurated on 14 April 1943; its principal promoter and first director was the historian Agustí Duran i Sanpere. It belongs to the City Council of Barcelona, as part of the Culture Institute.

Beginning at the time of the 1888 Barcelona Universal Exposition there were several attempts and projects to create a museum about the history of Barcelona. MUHBA was the first of these actually to come to fruition.

In 1929, during the 1929 Barcelona International Exposition the municipality organized a temporary exhibition about Barcelona's past, present and future that constitutes the forerunner of MUHBA.

In 1931, Casa Padellàs, a late gothic palace (15th-16th centuries) was moved stone by stone from its original location on Mercaders street to Plaça del Rei, in order to preserve it and to avoid its demolition because of the opening of Via Laietana, an avenue that crosses through the old city to connect the new Barcelona Eixample with the port.

While rebuilding Casa Padellàs on its new location, some remains of the ancient city of Barcino (Latin name of Barcelona) were found. Immediately, archaeological research was undertaken in the surrounding area, exposing a whole quarter of the Roman city. The Spanish Civil War (1936-1939) put an end to this research, though the importance of the findings determined that this was the most fitting location for the historical museum planned since the 19th century, which would then become largely an archaeological museum.

The Museum of the History of Barcelona was finally inaugurated several years after the civil war, in 1943, under the Francoist regime. The core of the museum was then centered on the archaeological remains of the Roman and late antique city together with the medieval royal palace in Plaça del Rei (Palau Reial Major), which includes the main hall called Saló del Tinell (14th century) and the palatine chapel dedicated to Saint Agatha (14th century) with its 15th-century Gothic altarpiece, a work of the medieval painter Jaume Huguet. Several rooms of the rebuilt Casa Padellàs also exhibited objects bearing witness to the history of Barcelona along late medieval and modern times, up to the early 20th Century: the city government and its regulations, the guilds, civic celebrations, wars and conflicts, crafts and trade, the International Expositions held in Barcelona and the growth and transformation of the city in the industrial era, among other topics.

The museum gradually incorporated new sites such as the Temple of Augustus and the Roman sepulchral way in Vila de Madrid square (found in 1954). The archaeological zone at the Plaça del Rei also grew, with new discoveries such as the Early Christian baptistery (1968).

After Franco died in 1975 and democracy was restored in Spain (particularly since 1979), the role of the museum was reconsidered. The permanent static exhibition about the history of Barcelona in the rooms of Casa Padellàs was closed around 1990. Since 1996 Casa Padellàs's rooms serve for temporary exhibitions that allow more dynamic overviews and crossed discussions about key subjects of Barcelona's history. Simultaneously, the archaeological area was completely remodelled and its museography updated, incorporating recent knowledge about the city in Roman and late antique times; the remodelled exhibit opened in 1998.

In recent decades, MUHBA has put more focus on contemporary history while simultaneously growing as a network of heritage sites, tending to provide through them a more complete coverage over the History of Barcelona.

Since 2005 MUHBA has published the scientific magazine Quarhis (Quaderns d’Arqueologia i Història de la ciutat de Barcelona) as an updated successor to the former magazine Cuadernos de Arqueología e Historia de la Ciudad (1960-1980)

MUHBA impulses a European network of city history museums and research centers on urban history (since 2010).

The Museum of the History of Barcelona has several heritage sites spread all around the city. Most of them are archaeological sites displaying remains of the ancient Roman city, called Barcino. Others refer to medieval times and the rest cover the contemporary city, including old industrial buildings and sites related to Gaudí and the Spanish Civil War.

• MUHBA Plaça del Rei. Located in the Gothic Quarter, Ciutat Vella district. Headquarters of the Museum.
