Bent's Old Fort National Historic Site is located in southeastern Colorado, near the Arkansas River. This reconstructed adobe fort was originally built in 1833 by the Bent brothers, William and Charles, as a trading post for fur traders and Native Americans. The fort played a significant role in the westward expansion of the United States and served as a hub for commerce and cultural exchange. Today, the site offers visitors a glimpse into 19th-century life on the frontier. The fort features living history demonstrations, guided tours, and educational programs that highlight the interactions between Native Americans, fur traders, and settlers during this pivotal time in American history.
