The municipality includes the village Köngen, the yards Birkenhöfe, Buchenhöfe, Erlenhöfe, Kempflerhöfe, Lerchenhof, Riedhöfe, Rothöfe, Seehof, Talhof and Wangerhöfe and the house Altenberg.

According to data from the Statistical State office, effective 2014.

Köngen is in the area of the Roman settlement Grinario that was built around 100 AD around a Roman castra. Grinario was the endpoint of the Roman road "Neckar-Alb-Aare" which originated in Windisch (Switzerland). In 260 the place was destroyed by the Alemanni and the Romans were expelled.

The Alemanni place was first mentioned in 1075 in a document of the Hirsau Abbey. In 1336 the lords of Hohenberg sold the village to Albrecht von Aichelberg. In 1382 the lords of Thumb von Neuburg [de] attained the sovereignty, who relocated their residence from Grisons to Köngen in 1430. Hans Friedrich Thumb promoted early the Reformation; already in 1527 was therefore preached Lutheran in Köngen, this is seven years before Duke Ulrich penetrated in 1534 the Reformation in Württemberg.

Around the year 1600 about 900 people inhabited the village. During the 17th century Köngen suffered from several outbreaks of diseases and war violence. From 1609 until 1611 there was a first plague outbreak, the second one happened in 1627. About one third of the population died from the disease. Over one hundred inhabitants were killed by marauding troops of the victorious emperorer after the Battle of Nördlingen in 1634. The number of 1,000 inhabitants was only passed during the first half of the 18th century. 1739 Köngen became part of Württemberg, at this time the former owners (Thumb von Neuburg) had already been in Württemberg service for more than 200 years. After the foundation of the Kingdom of Württemberg in 1806 until 1808 Köngen was seat of an Oberamt. During the consolidation phase of the new württembergian administration it was allocated to the Oberamt Esslingen [de], which was as part of the Kreisreform (county reform) during the National Socialist time in 1938 changed and enlarged to the district of Esslingen. Because Köngen became part of the American occupation zone after the Second World War, it belonged to the state of Württemberg-Baden, founded in 1945 which in 1952 merged into today's state of Baden-Württemberg.

Since the Reformation Köngen has been mostly Lutheran. Only since 1953 there has been a catholic church again. The new building became necessary because of the relocation of many catholic Heimatvertriebene ("homeland expellees"). Furthermore, there are a United Methodist Church and since 1924 a New Apostolic Church.

Blazon: "In blue a silver bell".

Köngen has the largest bell of its Peter-und-Paulskirche in its coat of arms. This bell is supposed to have been buried during the Thirty Years' War for fear of marauders. When the war was over no one was alive anymore who knew the hiding place. The lost bell was then uncovered from the ground, according to legend, by pigs. Since then the bell is named Sauglocke ("sow bell").

Köngen maintains partnerships to:

• Taucha in Saxony-Anhalt and
• Český Brod in the Czech Republic.

• Köngen is located at the Neckar line of the Upper Germanic-Rhaetian Limes. In the town the 23 km (14 mi) long Lautertal Limes line splits off from the Neckar line, which ends at the Alb Limes at Donnstetten [de] (a parish of Römerstein). This straight path had already been known as Sibyllenspur for a long time prior to its interpretation as Limes in 1976.
• Köngen is start and end point of the scenic route Römerstraße Neckar–Alb–Aare [de; la].
• Notable are two replicas of Jupiter Columns:
  • Replica of the Jupiter Column of Hausen an der Zaber [de] on top of the roundabout at the Plochinger Straße.
  • Replica of the Jupiter Column of Walheim [de] in front of the reconstructed guard tower in the southeast corner of the roman park.
• Roman Museum and Archeological Park Köngen [de]. The Castra of Köngen [de] has been a Kulturdenkmal (cultural monument) since 1974 and is the only castra along the entire Neckarlimes not being over built after the war. It is as a military camp at the roman Limes part of the UNESCO World Heritage since 2005. The corner tower of the old garrison was found in 1885 by general Eduard von Kallee and already reconstructed in 1911.
• The Köngen Palace [de] was first constructed in 1392 as a castle by the local lord, the Free Imperial Knight Hans Thumb von Neuburg. The Neuburg still exists today as a ruin north of Chur in Grisons. Already in 1398 the castle was expanded to a water castle with four wings. In 1520 the castle was heavily damaged by troops of the Swabian League. Therefore, an almost entirely new construction was built after 1520. The castle changed into a Renaissance palace. During this construction the great hall was expanded in 1538, which has survived almost unchanged up to today. The changes took almost the entire 16th century. Heinrich Schickhardt [de; es; fr; it; pt] mentioned in his catalogue that he had built a gate house at the palace around 1600. It was torn down together with two wings during the changes made by Jakob Friedrich Weishaar [de]. Weishaar bought the estate in 1825 and let it be changed according to his needs. Up to the 1930s it was a place for culture. Here the youth association "Bund der Köngener [de]" was established. The painter Christian Mali and the Dutch-German painters family Peters stayed often in the palace. During the last few years, frescos from the 18th century on the eastern wall of the great hall have been uncovered and restored. They show figures out of antique mythology and history.
• The foundation stone for the protestantist church Peter- und Pauls-Kirche was laid in 1502 by the builder Stefan Waid [de]. After his death in 1504 it was finished by builder Merx from Esslingen until 1512. The dimensions of the nave are 23.0 m (75.5 ft) times 12.1 m (40 ft). Unter a king post a painted renaissance beam ceiling is hanging since 1613. The western tower was constructed in 1724. The originally late Gothic carved altar was remodeled in 1614. The architects Kreuz + Kreuz from Stuttgart conducted the latest internal renovations in 2011. Features: The sculptor Martin Scheible [de] from Ulm created a pulpit with carved reliefs in 1953 (topics: the works of mercy); the renaissance pulpit ceiling remained. The glas artist Wolf-Dieter Kohler [de] from Stuttgart designed the glas paintings of the three choir windows in 1958 (left: three parables; middle: returning Christ, Angel, Michael; right: three further parables).
• The cultural heritage listed Ulrichsbrücke, a bridge over the Neckar river, was constructed according to plans by Heinrich Schickhardt between 1600 and 1602. It is located at the place of an earlier roman bridge. Due to impoundment downstream the pillars of the bridge are nowadays partially under the water level.
