Fort Union National Monument


Exposed to the wind, within a sweeping valley of short grass prairie, amid the swales of the Santa Fe Trail, lie the territorial-style adobe remnants of the largest 19th century military fort in the region. For forty years, 1851-1891, Fort Union functioned as an agent of political and cultural change, whether desired or not, in New Mexico and throughout the Southwest.
