A large town square named after the imposing Courthouse building most famously seen in Back to the Future (1985-1990). The square has been seen in hundreds of Universal films (and those of other studios). In common with many other standing sets, simple changes like the arrangement of street furniture and signage can make the set appear to be a completely different location.
Prior to Back to the Future, the area was known as Mockingbird Square, after it's appearance in To Kill a Mockingbird.
It's currently appearing in the CBS TV drama Ghost Whisperer.

Although the devastating fires in 1990 and 2008 destroyed the New York Street area, the Courthouse itself was spared, and looked even more magnificent amid the ashes.

To the south of Courthouse Square is New York Street.
