Granada Relocation Center, Colorado


The first internment camp in operation was Manzanar, located in southern California. Between 1942 and 1945 a total of 10 camps were opened by the War Relocation Authority, holding approximately 120,000 Japanese Americans for varying periods of time in California, Arizona, Wyoming, Colorado, Utah, and Arkansas. (

  •  “Assembly Center” was the name the government gave to the temporary housing that those of Japanese ancestry were held before the more permanent “Relocation Centers” were complete.
  • These makeshift centers were often built in fairgrounds and race tracks with inmates living in horse stables or hastily constructed barracks. (
  •  Other sites included Department of Justice Camps, U.S. Army sites, and federal Prisons.


Newest Update: Amache National Historic Site Formally Established as America’s Newest National Park 


President Biden signed the Amache National Historic Site Act in March 2022, designating the Amache site as part of the National Park System. This act will permanently protect that site for future generations and help tell history of Japanese Incarceration During World War II.

Executive Order 9066, signed by President Roosevelt on February 19, 1942, led to the forced removal of all persons of Japanese ancestry from the West Coast to one of 10 incarceration sites administered by the War Relocation Authority within 7 states.  The government’s validation for the imprisonment was “insufficient assimilation,” but was viewed by many as looking like the enemy. Granada, in southeastern Colorado, became home to over 7,000 persons from 1942 – 1945, making it the 10th largest city in Colorado. It was renamed Amache by General Prowers in honor of his Native American wife.

“Construction of the evacuee buildings at Granada differed from the other relocation centers. Instead of post-and-pier foundations, barracks had slab foundations, or concrete perimeter foundations with brick floors. The evacuee buildings also had fibre board or asbestos shingle siding, rather than the tarpaper common at most of the other relocation centers.”1 p. 106

Granada/Amache also had “one of the largest and most diversified agricultural enterprises of the ten relocation centers. The farm program included the raising of vegetable crops, feed crops, beef and dairy cattle, poultry, and hogs.” 1 p. 110-11

The aforementioned conditions allowed Amache, located only halfway across the country, to be a “showcase” camp for politicians desiring to check on the status of the camps.

In 1983, a 10’ tall monument inscribed with “Amache Remembered” was placed at the cemetery by The Denver Central Optimists Club.  Granada High School teacher, John Hopper, began researching Amache with his experience-based classes.  The project has grown from a scale model of the camp to the Amache Preservation Society which also houses a museum.

The state of Colorado provided funds to improve access and refurbish some of the site in 1994 and the Denver Optimist Club received a grant from the Civil Liberties Public Education Fund to develop the site for visitors. In 2006, it was recognized as a National Historic Landmark. In 2020, the National Parks Service began the study of its potential inclusion within the national park system.
