A nice mansard, although I am not crazy about the shingling on the taller part of the building. The church spire is part of the Ste. Genevieve Catholic church.
I thought I had been to most courthouses in Missouri. That is, until I scrolled through this list of courthouses and realized that at most I've been to only 30 of the roughly 120 courthouses in our state. I spent way too much time scrolling through the great photographs and histories. Be sure look at the photo of the above mansard with its original cresting and roof.
