I had always heard about this theater, but had never been by. In fact, Virginia Avenue is really amazing along this stretch, featuring some great architecture.
Originally built by Anheuser-Busch, it was bought by Wehrenberg and operated as a theater for years. Supposedly several churches occupied the space as well, but I saw no evidence of occupation when I drove by in early February. Read about the theater here.
If you look closely, you can see the back stage rising above the rest of the building.
