The Bürgerbräukeller (ˈbʏʁ.ɡɐ.bʁɔʏ̯.ˌkɛ.lɐ; "citizen brew cellar") was a large beer hall in Munich, Germany. Opened in 1885, it was one of the largest beer halls of the Bürgerliches Brauhaus. After Bürgerliches merged with Löwenbräu in 1921, the hall was transferred to that company. The Bürgerbräukeller was where Adolf Hitler launched the Beer Hall Putsch in November 1923 and where he announced the re-establishment of the Nazi Party in February 1925. In 1939, the beer hall was the site of an attempted assassination of Hitler and other Nazi leaders by Georg Elser. It survived aerial bombing in World War II. The Bürgerbräukeller was demolished in 1979, and the Gasteig complex was built on its site. The Bürgerbräukeller was located in the Haidhausen district of Munich on the east side of the Isar River. The entrance was from Rosenheimer Street, with rear access from Keller Street. Since 1980, the site has been redeveloped with the construction of the Gasteig Culture Centre, the Hilton Munich City Hotel and the headquarters of GEMA. As early as the 16th century, brewers in Bavaria would collect the barrels of beer near the end of the brewing season and stock them in specially developed cellars for the summer. By the 18th century, brewers discovered they could make a greater profit if they opened their garden-topped cellars to the public and served the beer on site. In the 20th century, the Bürgerbräukeller had both a cellar and a beer garden, as well as the grand hall for indoor functions. The grand hall was a rectangular space accommodating up to 3,000 people, though less in full dining mode. Freestanding pillars on either side of the hall supported narrow galleries and the roof. The load-bearing walls and the internal pillars with classical capitals were plastered brickwork. A decorative plastered ceiling, divided into bays with three rows of chandeliers, concealed steel beams supporting the timber roof structure. From 1920 to 1923, the Bürgerbräukeller was one of the main gathering places of the Nazi Party.
