How many courthouse structures have been built on the site of the current Greene County Courthouse?



There have been three courthouses built where the Greene County Courthouse stands today.  Ground was broken on the current courthouse in November of 1915, the cornerstone was set in May 1916 and the new building was dedicated in October of 1917. The centennial celebration of the courthouse is already underway, with events being planned by the “Courthouse 100” committee, with support from the Greene County Historical Society.  You can learn more about the courthouse history and the celebration plans on the Facebook page “Courthouse 100: Greene County, Iowa.”
