The Odeonsplatz is a large square in central Munich which was developed in the early 19th century by Leo von Klenze and is at the southern end of the Ludwigstraße, developed at the same time. The square is named for the former concert hall, the Odeon, on its northwestern side. The name Odeonsplatz has come to be extended to the parvis of the Residenz, in front of the Theatine Church and terminated by the Feldherrnhalle, which lies to the south of it. The square was the scene of a fatal gun battle which ended the march on the Feldherrnhalle during the 1923 Beer Hall Putsch.
