Excavations were completed in 1994 adjacent to the Morris-Jumel Mansion located in Roger Morris Park in Washington Heights, Manhattan. The Mansion was built in 1765 and is famed for having served as General George Washington’s headquarters for a month in 1776. Previously undocumented structures on the site were discovered during the testing including two 19th century cobble walkways and artifacts dating to the Late Archaic period. The site is open to the public. For more information, please see: Archaeological Investigations: Foundation Waterproofing Project Morris-Jumel Mansion
