Bent's Old Fort National Historic Site

Bent's Old Fort is a meticulously reconstructed adobe trading post on the north bank of the Arkansas River in southeastern Colorado, just outside modern La Junta. The original structure was built in 1833 by brothers William and Charles Bent alongside Ceran St. Vrain to serve as a fixed hub on the Santa Fe Trail, exchanging bison hides and beaver pelts for manufactured goods with Cheyenne traders, trappers, and Mexican merchants. During the Mexican–American War in 1846 it served as General Kearny's staging base before the march on Santa Fe; within two years the fort was mysteriously abandoned and burned — whether by Bent himself or others remains disputed. The National Park Service now oversees the reconstructed site, staffed by costumed rangers demonstrating blacksmithing, trade negotiations, and 1840s frontier life. The Arkansas River and open prairie surrounding the fort add a genuine sense of geographic remoteness.
