One of the oldest US theaters in operation, the Castro Theatre is a historic movie palace in the Castro District of San Francisco, California. The venue became San Francisco Historic Landmark #100 in September 1976.

The Castro Theatre originally opened at 479 Castro Street in 1910.[5][6] It was subsequently remodeled into a retail store (currently occupied by Cliff's Variety, since 1971) in the mid-1920s after the larger Castro Theatre was built at 429 Castro Street, its current location, only a few doors up from the original theatre.
