The first Pennsylvania state park, at Valley Forge, opened in 1893 and was given to the National Park Service (NPS) for America's bicentennial in 1976. There are a total of seventeen former Pennsylvania state parks: four former parks have been transferred to the NPS, four to the Pennsylvania Historical Museum Commission, two to the U.S. Army Corps of Engineers, one to both the Corps and the Pennsylvania Game Commission, five to the Pennsylvania Bureau of Forestry, and one has ceased to exist. Nine current and two former state parks have had major name changes or have been known under alternate names.
