Canajoharie, also known as the "Upper Castle", was the name of one of two major towns of the Mohawk nation in 1738. The community stretched for a mile and a half along the southern bank of the Mohawk River, from a village known as Dekanohage eastward to what is now Fort Plain, New York. The modern village of Canajoharie, New York was settled by European Americans a few miles to the east of the historic Mohawk village.
