Pennsylvania's first state park was Valley Forge State Park, purchased by the Commonwealth on May 30, 1893 to preserve Valley Forge. It was transferred to the National Park Service (NPS) on the Bicentennial of the United States, July 4, 1976. Many state parks still preserve history: as of 2012, forty-two Pennsylvania state park sites are on the National Register of Historic Places, including two National Historic Landmarks (Delaware Canal and Point), twenty-eight Civilian Conservation Corps sites in nineteen parks, and twelve other parks' historic sites and districts. Eight of the former state parks were also chiefly historic.
