Museum devoted to the 160-year history of Stanstead Grey Granite, including the architecturally-notable buildings which used the stone. A second museum on-site claims the largest HO-scale Lionel miniature model train museum collection in Canada.

International library established by American sawmill owner Carlos Haskell and his Canadian wife Martha Stewart Haskell. The library has an English and French collection of more than 20,000 books; a black line across the library floor denotes the international border. The opera has most of its audience seats on the American side, and the stage is on the Canadian side. The building is registered as a historical site in both countries. There is no charge to borrow materials, no membership fees, but payment may be required to watch opera performances.
