A National Historic Landmark, the 1812 John Wickham House is a stunning example of Federal architecture that allows guests to explore life in the early 19th century. Designed by Alexander Parris for attorney John Wickham, a prominent lawyer who helped defend Aaron Burr against treason charges in 1807, this Neoclassical building was home to Wickham's family and more than 15 enslaved African Americans. Entrepreneur Mann S. Valentine II purchased the property in 1882 and displayed his archaeological and ethnographic collections here. In 1898, the house became the first home of the Valentine Museum. Today, the 1812 John Wickham House continues to be part of the Valentine's permanent collection.
