Monroe is situated in southwest Ohio, in Butler County, and a small portion is also within northwest Warren County. The City of Monroe was founded in 1817 It has three museums and a memorial to the Vietnam Veterans in the region.
Originally Monroe was within the limits of Lemon Township which was the largest in Ohio. There is not much of Lemon Township that exists today with most areas having been annexed into the Monroe proper. Pioneer John Baker (1775-1852) is believed to be the first inhabitant of the area.
There are three museums located nearby: the Log Cabin Museum, the 1917 House, and the Chickahominy house. Each of these museums are under the guardianship of the Monroe Historical Society.
