The Castle Amphitheater, sometimes called the Provo Castle, is a unique historical building found on the grounds of the Utah State Hospital in Provo, Utah.
The Castle Amphitheater was constructed between 1936-1937 and was one of around 230 public works constructed in Utah under New Deal programs. The amphitheater could seat around 800 people and had several interior rooms.
During the 1970s, the Castle Amphitheater was used as a “haunted castle” during Halloween. The haunted castle was open to the public with all proceeds going towards the hospital’s recreation funds.
Today, the Castle Amphitheater is open to the public, but visitors must check-in at the Utah State Hospital at the main administration building. Visitors can explore and roam the amphitheater, unless a public or private event is taking place.
