Old Fort Johnson

Old Fort Johnson was built by William Johnson in 1749 beside the Mohawk River in colonial New York.  The original limestone house was fortified for protection during the French & Indian Wars from 1755-63. King George II rewarded Johnson with the title of Sir William, Baronet of New York, for his role in the Battle of Lake George in 1755. His later actions led to another British victory at Fort Niagara. Sir William Johnson convened many Native American conferences on this site as the British Superintendent of Indian Affairs for the Northern Department. 

Old Fort Johnson was one of four Johnson family homes in the Mohawk Valley. Sir William moved to Johnson Hall at Johnstown in 1763. His son John remained at Old Fort Johnson, removing the last of the fortifications and renovating the house for his marriage in 1772. The family remained loyal to the British Crown during the American Revolution. Their properties were seized by American patriots and the contents sold at auction. 

Old Fort Johnson remained in private hands until 1906 when it was opened to the public as a historic house museum by the Montgomery County Historical Society. It has been maintained by this nonprofit organization ever since, funded largely by memberships, donations and private fund-raising efforts. Listed as a National Historic Landmark, the property receives no operating support from any federal or state government agencies.
