An official Path Through History Site! Mount Gulian is a reconstruction of the 18th-century Dutch house that served as headquarters of Major General Friedrich von Steuben, drillmaster of the Continental Army in 1783. Here, officers founded the Society of the Cincinnati, a fraternal veterans` organization. The interior contains items given to Gulian Verplanck by Native Americans. Mount Gulian also interprets the life and history of escaped slave, James F. Brown, whose detailed journal is one of very few African-American written records.
