I would be remiss if I didn't post about Seneca's other notable historic site: the Hogan Grain Elevator (see photos to the right).
Built in 1862, this grain elevator, which is listed in the National Register of Historic Places, is one of the last of the old 19th century grain storage structures in Illinois. It sits right on the Illinois & Michigan Canal, and adjacent to the railroad tracks. It's 65-feet tall and could store about 70,000 bushels of grain.
There are the remains of a short railroad track from the grain elevator to an old dump shed. Also photographed above is the old office that sits next to the grain elevator.
