Peace following the French and Indian War (1756–1763) provided security on the frontier, and in 1764, Nicholas Herkimer constructed the Georgian style mansion you see here. The house remained in the Herkimer family until 1814. It then passed through a succession of owners who considerably altered it inside and out. When the State of New York purchased the property in 1913, the mansion was in very poor condition.The first restoration activities were undertaken in 1914-1915. In the 1960s, efforts were made to return the structure to its 18th-century style, which resulted in the historic house's present-day appearance.
