Fort Union was established in 1851 by Lieutenant Colonel Edwin V. Sumner as a guardian and protector of the Santa Fe Trail. During it's forty-year history, three different forts were constructed close together. The third and final Fort Union was the largest in the American Southwest, and functioned as a military garrison, territorial arsenal, and military supply depot for the southwest. Today, visitors use a self-guided tour path to visit the second fort and the large, impressive ruins of the third Fort Union. The largest visible network of Santa Fe Trail ruts can be seenhere.
