County Information
Warren County was formed May 1, 1803, from Hamilton County.
It was named for Dr. Joseph Warren, a hero of the Revolution who sent Paul Revere on his famous ride and who died at the Battle of Bunker Hill.
The county seat is Lebanon.

On Little Miami River

The major rivers of the county are the Great Miami River, which flows through the northwest corner of the county in Franklin Township, and the Little Miami River which zig-zags across the county from north to south. There is one sizable lake, the Caesars Creek Reservoir, created by a U.S. Army Corps of Engineers dam on Caesars Creek in the northeast part of the county in Massie Township.

Kings Island Theme Park is in this county, opening in 1972.
