Camp Chase was a military staging and training camp established in Columbus, Ohio in May 1861 after the start of the American Civil War. It also included a section for use as a prison camp during the American Civil War. The camp was closed and dismantled after the war, and the site has been redeveloped for residential and commercial use, except for the Confederate cemetery containing 2,260 graves. The Camp Chase Cemetery is located in what is now the Hilltop neighborhood of Columbus, Ohio. The Camp Chase Site, including the cemetery, is listed on the National Register of Historic Places.
