William Sidney Mount House, Historic house museum in Stony Brook, United States

The William Sidney Mount House is a two-and-a-half story residence with twenty rooms, wooden shingle exterior, and two brick chimneys rising from the roof. The structure displays architectural phases from different periods and preserves the original kitchen and the artist's working studio.

Built in 1725 as a tavern, the house later transformed into a residence with a significant expansion around 1810. It received National Historic Landmark status in 1965.

The attic workspace shows how William Sidney Mount organized his painting practice focused on rural American scenes. You can see the actual place where he worked and stored his materials for daily creative life.

The house is located on Stony Brook Road and managed by the Long Island Museum, which offers regular guided tours. Plan your visit in advance since access is through scheduled tours that show the original rooms and workspaces.

Mount added a skylight to his attic workspace and custom shelf brackets that still hold his experimental color samples. These details reveal how the artist tested and organized his paint mixtures while working on paintings.
