Lincoln Square, Decatur, Illinois, about 1920
Another photo from the antique store.
The domed structure is “The Decatur Transfer House” for the city's street car line. It still exists, although it was moved to a nearby park in 1962. The other notable structure in the picture, “The Lincoln Square Theatre” was built in 1916. It also still exists and is being restored.
It is said to be haunted.
