The Pultneyville Historical Society seeks to preserve and present the history of Williamson Township, New York. To this end, the society offers exhibits within a circa 1858 home. Exhibits address the life and work of Horatio Nelson Throop, the 1898 loss of the schooner St. Peter, and local history as depicted through photography. Throop was a boat builder and captain. In the 1830s, he conducted experiments with wind and screw propeller propulsion systems. He was also active in the Underground Railroad. The society owns a collection of artifacts recovered from the wreck of the St. Peter.

The society offers exhibits and archival access. Appointments are required for archival access.
