The courthouse lawn contains a Posey County Civil War Memorial (Liberty Monument) erected in 1908, and a Soldiers of American Revolution monument.
The county seat was relocated twice because Blackford was not centrally located and Springfield did not have the prerequisites to become a thriving town.
