Fort Lyon, first named Fort Wise, has served in Colorado as a United States Army fort, a sanatorium, a neuropsychiatry facility, and a minimum security prison. The state closed the prison in 2011, and in early 2013 proposed to use the site as a rehabilitation center for homeless people. Then in late 2013 became a rehabilitative transitional housing facility for homeless people with some form of substance abuse problem(s). This is run by the Colorado Coalition for the Homeless and has been a developing program to current day. The fort is listed on the National Register of Historic Places.
