Fort Selden was established in 1865 in an effort to bring peace to the south-central region of present-day New Mexico. Built on the banks of the Rio Grande, this adobe fort housed units of the U.S. Infantry and Cavalry. Their intent was to protect settlers and travelers in the Mesilla Valley from desperados and Apache Indians. Several of the units stationed at the fort were black troopers, referred to as Buffalo Soldiers. A young Douglas MacArthur called the fort home while his father was post commander in the late 1880s. By 1890 criminals and raiding parties were no longer considered a threat as hostilities eventually lessened and the fort was no longer needed. Like many small forts in the Southwest the government decommissioned the fort and it was abandoned in 1891. Today the stark adobe brick walls of the frontier past evoke a feeling of personal connection to the past. A visitor center offers exhibits on frontier and military life.

The site offers exhibits and occasional recreational and educational events (including living history events).

he Newark Earthworks were the largest set of geometric earthen enclosures in the world. Built by prehistoric Hopewell people between 100 BC and AD 500, this architectural wonder of ancient America was part cathedral, part cemetery, and part astronomical observatory.

Originally covering more than four square miles, today only three major segments are preserved: Great Circle Earthworks, (formerly known as Moundbuilders State Memorial), Octagon Earthworks, and Wright Earthworks.
Maintained by the Ohio Historical Society since the 1930s, these sites are the best preserved examples of the monumental geometric earthworks of the Hopewell culture. The surviving parts of the Newark Earthworks are recognized as a National Historic Landmark. In 2006, the State of Ohio designated the Newark Earthworks as "the official prehistoric monument of the state."

Learn more about the Newark Earthworks by visiting the Great Circle Museum. Visitors are invited to watch an interactive video explaining the significance of the site and tour a 1,000-square-foot exhibit that includes a timeline of Ohio's ancient cultures and an explanation of why American Indians regard the Newark Earthworks as a sacred site. The exhibit also details how the earthworks align with the rising and setting of the moon. Following the museum tour, visitors can take self-guided tours of the grounds during daylight hours.
