Alex Fries sent me this picture of the second building od St. Peter's Church, in Norwalk, which was built in 1868. The parish apparently didn't last long, afterward. This shows that, even that far back, churches didn't always look like churches. I've learned that, sometimes, a parish, planning new buildings, would build the school first. It was easier to use a school building as a temporary church, than the other way around. In this case, they didn't last long enough to build another proper church.
