The Gouverneur Museum collects and preserves historical artifacts from the Gouverneur area.
The Gouverneur Museum building was was formerly the Presbyterian Manse. The home was originally given to the church by the Dean family. The home was given to the church by the Dean sisters, Cora and Jennie, and their mother, Mira Aldrich Dean. The Gouverneur HIstorical Association purchased the building for a museum in 1974.
The Museum has artifacts on three floors, a building in the back and an Annex at the Gouverneur and St. Lawrence County Fairgrounds. Thanks to the generosity of area residents, the museum houses thousands of items, many quite unique.
