Now THAT sounds like a real monster! Glad it was saved.^^^^^
I'll look for it.
The 1920's era high school in the next town east from us was a castle like that. the auditorium was humongous. Full fly system over the stage, I think a functioning orchestra pit elevator, and a bleeping pipe organ. They were not just schools, they were centers of civic pride. Fortunately that structure was saved; it became luxury condos. I don't know what they did with the auditorium though.
