Courthouse Square is a backlot located at the Universal Studios Lot in Universal City, California. The set is composed of several facades that form an archetypal American town square with a courthouse as its centerpiece. The set was built for the 1948 film An Act of Murder and was featured as downtown Hill Valley in the Back to the Future trilogy, as well as Kingston Falls in the Gremlins series.[1]
Prior to the Back to the Future series, the area was known as Mockingbird Square owing to its role in the film To Kill a Mockingbird. It has been severely damaged by fire several times, including in 1957, 1990 and 2008. It was reconstructed after each incident.
