Public Auditorium (also known as Public Hall) is a multi-purpose performing arts, entertainment, sports, and exposition facility located in the civic center district of downtown Cleveland, Ohio. The 10,000-capacity main auditorium shares its stage with a second venue housed at the facility: the 3,000-capacity Music Hall. Although Public Auditorium was planned and funded prior to World War I, construction did not begin until 1920, and the building did not open until 1922.
