 A fully functioning replica kitchen, as Washington might have known it while he was a guest of the DeWints, was completed in 1996.The grounds include a 19th-century carriage house that contains displays of artifacts uncovered at the site during archaeological digs, as wells as items related to Washington, André and Arnold, and the Masons.A large mill stone from a grist mill in nearby Ramapo is displayed on the grounds, and at the rear of the house stand seven small grave markers each bearing one to three initials, which came from a nearby property.
