Brühl received its town privileges in 1285. From 1567 on, the city of Brühl was the official residence of the Prince Bishops of Cologne. In the 18th century the Prince Bishop Clemens August replaced a former ruined castle and built the Augustusburg and Falkenlust palaces near the city center. Today, both are listed as UNESCOWorld Heritage Sites because of their outstanding rococo architecture. Until 1990 Augustusburg Palace was used by the federal government to receive foreign heads of states visiting West Germany.
The Max Ernst Museum, opened in 2005. It displays sculptures and paintings of the surrealistic artist Max Ernst (who was born in Brühl) and other modern art.
Local history and pottery are shown in two small museums in the city centre
