Granada War Relocation Center, known to the internees as Camp Amache ( ah-mah-chee) and later designated the Amache National Historic Site, was a concentration camp for Japanese Americans in Prowers County, Colorado. Following the Japanese attack on Pearl Harbor on December 7, 1941, Japanese Americans on the West Coast were rounded up and sent to remote camps. The camp, located 1.3 miles (2.1 km) southwest of the small farming community of Granada, south of U.S. Highway 50, was listed on the National Register of Historic Places on May 18, 1994, and designated a National Historic Landmark on February 10, 2006. On March 18, 2022, U.S. President Joe Biden signed the Amache National Historic Site Act authorizing the Granada War Relocation Center to become part of the National Park System. It was formally established as part of the National Park Service on February 15, 2024, the third National Historic Site in Colorado after Bent's Old Fort and the site of the Sand Creek Massacre.
