- Historical Site,
Fort Union was established in 1851 as the guardian of the Santa Fe Trail. During it's forty-year history, three different forts were constructed close together. The third Fort Union was the largest in the American Southwest, and functioned as a military garrison, territorial arsenal, and military supply depot for the southwest. The largest visible network of Santa Fe Trail ruts can be seen here.
