Fort Union National Monument

National Monument · New Mexico · National Park Service

Exposed to the wind, within a sweeping valley of short grass prairie, and along the eroded Santa Fe Trail, lie the adobe walled ruins of the largest 19th century military fort in the region. From 1851 to 1891, Fort Union functioned as an agent of change, desired or not, in the New Mexico Territory and throughout the Southwest.
