The Washington County Historical Society is a vibrant, educational, non-profit organization, chartered by the NYS Board of Regents in 1940. Its primary purpose is to promote public interest and participation in the preservation of the rich cultural heritage of Washington County, NY. The Heritage Research Library, a repository for regional books, written documents, genealogical information, and memorabilia, and the publication of eighteen books highlight preservation efforts. Lectures, workshops, tours and social events are scheduled throughout the year.

Society headquarters are situated in the Wing-Northup House, built by entrepreneur Daniel Wood Wing c. 1815. This architecturally significant Federal style house is located in Fort Edward, New York, on Route 4, about fifteen minutes from Exit 17 of NYS 87 or Northway and is adjacent to the Fort Edward Yacht Basin.
