The 19^th century Red Barn was built originally as a grain storage shed located on the Orient Wharf and subsequently moved 750 feet to its present location on the OHS campus. In the most recent past, the building stored some of the larger scale objects in OHS’s collections, including horse-drawn carriages and sleighs.

In 2024 it was revitalized and repurposed and is now home to the multi-media Red Barn Collection, a permanent exhibition focusing on the storied farming and fishing history of Long Island’s North Fork.
