Collinsville City Hall

Many of the original buildings from the late 1800s and early 1900s remain in use today. Collinsville's downtown is one of the few that retain the majority of its historic buildings. City Hall is housed in a historic structure built in 1913 and located on the western edge of the downtown area.

The front of the building shows this building as the City Hall, but engraved above that name it shows what the building has also been used for. Besides sharing the building with the police department, what else shared space in this building according to the engravement?
