Mohawk Upper Castle Historic District

Mohawk Upper Castle Historic District is a historic district in Herkimer County, New York that was declared a National Historic Landmark in 1993. Located south of the Mohawk River, it includes the Indian Castle Church, built in 1769 by Sir William Johnson, British Superintendent of Indian Affairs, as a missionary church for the Mohawk in the western part of their territory; the Brant Family Barn, a rare surviving example of Dutch colonial barns in the Mohawk Valley; as well as important archaeological site areas revealing life in Nowadaga, as the western part of the Mohawk village of Canajoharie was known. The fortified village was called the Upper Castle by European colonists.

Its name differentiates it from Lower Castle to the east, another fortified Mohawk village, known as Tionondoroge, near the confluence of Schoharie Creek and the Mohawk River. Fort Schuyler was built here in 1712. The Schoharie Crossing State Historic Site, containing remains of a navigable aqueduct, is near the former village location.
