Fort Massapeag Archeological Site in present-day Massapequa, Long Island, is widely believed to be the location of a mid-17th-century New Netherland trading post, possibly also used for making wampum. It is linked to a 1656 agreement between Peter Stuyvesant and the Lenape chief Tackapausha calling for a house or fort for trade with Native communities, which archaeologist Ralph Solecki identified with this site. The post appears to have remained in use until 1664. Later known as Fort Neck, the area drew major archaeological attention in the 1930s after development exposed Native graves and village remains. Preserved within Sunset Park, it was designated a National Historic Landmark in 1993.
