A wing of the Festsaalbau contains the Cuvilliés Theatre since the reconstruction of the Residenz after World War II. It also houses the Herkulessaal (Hercules Hall), the primary concert venue for the Bavarian Radio Symphony Orchestra. The Byzantine Court Church of All Saints (Allerheiligen-Hofkirche) at the east side is facing the Marstall, the building for the former Court Riding School and the royal stables.
