Castle Williams is a circular fortification of red sandstone on the northwest point of Governors Island, part of a system of forts designed and constructed in the early 19th century to protect New York City from naval attack. It is a prominent landmark in New York Harbor. Together with Fort Jay, it is managed by the National Park Service as part of Governors Island National Monument.
