History
Fort Lyon (1860–1867)

In July 1860, the Army rented
Bent's New Fort
Bent's New Fort was a historic fort and trading post along the banks of the Arkansas River in what is now Bent County, Colorado, about nine miles west of Lamar, on the Mountain Route branch of the Santa Fe Trail. William Bent operated a trading ...
and used it for storage of annuity goods for the Cheyenne and Arapaho.
Annuity goods were provided by treaties in exchange for reduced access to ancestral land, such as hunting grounds. Barracks were built around the fort
and additional defensive features were added, like diamond-shaped gun emplacements on newly-erected earthenworks that surrounded the fort.
At the same time (1860) the Army constructed a new fort about one-half mile west of Bent's New Fort adjacent to the Arkansas river, naming it Fort Wise for
Henry A. Wise, the governor of Virginia. After the start of the
American Civil War
The American Civil War (April 12, 1861 – May 26, 1865; also known by other names) was a civil war in the United States. It was fought between the Union ("the North") and the Confederacy ("the South"), the latter formed by state ...
and Virginia's succession from the Union, it was renamed Fort Lyon in 1862 for Brigadier General
Nathaniel Lyon, who had been the first Union general killed in the Civil War.
In 1861, the
Treaty of Fort Wise was signed at the fort. The goal, which was short-lived, was to ensure peace between settlers and the Cheyenne and Arapaho people.
Old Fort Lyon was the staging post used by Colonel
John Chivington in 1864 as he led an attack on friendly
Cheyenne

and
Arapaho camps that became known as the
Sand Creek massacre. To prevent word spreading of the impending attack, Chivington had guards posted at the fort to prevent people and mail from reaching Sand Creek.
In 1866 after flooding on the

, the U.S. Army relocated Ft. Lyon 20 miles upstream to a site near Las Animas. The new facility was completed in 1867 and the old site, including Bent's New Fort, was abandoned.
Fort Lyon (1867–1897)
In 1867, a new fort called Fort Lyon was built near the present-day town of
Las Animas, Colorado

Indian Wars.
Medical, prison, and psychiatric facilities
In 1906, the
U.S. Navy opened a
sanatorium there to treat sailors and marines with
tuberculosis

. The dry climate and rest by isolation at the fort were thought to be beneficial by contemporary treatment methods. On 22 June 1922, the Veteran's Bureau assumed operations. In 1930, administration of the hospital was transferred to the newly created
Veterans Administration. Within three years, the VA designated Fort Lyon a
neuropsychiatry facility. In 2001 the hospital was closed and the facility was turned over to the state of Colorado for conversion to a
minimum security prison
A prison, also known as a jail, gaol (dated, standard English, Australian, and historically in Canada), penitentiary (American English and Canadian English), detention center (or detention centre outside the US), correction center, correcti ...
. The prison was closed in 2011.
In September 2013, Governor
John Hickenlooper announced that Fort Lyon had reopened as an isolated transitional housing facility for homeless people with
substance abuse issues operated by the Colorado Coalition for the Homeless. As of November 2018, there were over 200 clients there.
