This Illinois State Police Headquarters was built in 1941.  Its Art Moderne architecture reflects the streamlined design of the automobiles of that era.

The most unique aspect of this building is that it's shaped like a pistol. Of course, the only way to see this is from the air.

The Illinois State Police (District 6) occupied this facility until 2003, when they moved to a newly constructed facility on the south-side of Pontiac, Illinois.

This historic building was listed on the National Register of Historic Places in 2007.
