Fort Selden Historic Site is at 1280 Ft. Selden Rd. Crumbling adobe walls are all that remain of the fort, which was built in 1865 and protected travelers and settlers in the Mesilla Valley from desperados and Apache Indians. After the war, African-American Buffalo Soldiers occupied the fort. As a boy in the 1880s, Gen. Douglas MacArthur also lived here while his father served as post commander. A visitor center displays military artifacts. Frontier Days at Fort Selden is celebrated in October with period encampments and re-enactments.
