Chateau de Mores, Historic residence in Medora, United States.

The Chateau de Mores is a two-story wooden house in Medora built by a French nobleman in the 1880s. The building contains original furnishings, artifacts, and personal belongings that document the family's life on the frontier.

A French nobleman established this residence in 1883 as the center for cattle ranching and meat processing in Dakota Territory. His ambitious business venture shaped the region's development during that era.

The residence shows how a European family adapted their lifestyle to life in the American West, mixing old traditions with frontier practicality. The rooms and their furnishings reveal how daily habits and tastes transformed across the ocean.

The house is operated as a museum by the State Historical Society of North Dakota, and guided tours are available. The site also takes in Chimney Park and de Mores Memorial Park, so allow time to walk between them. The building was restored in 1995.

Locals gave the house its grand name; it is not a true chateau. The 26-room wood-frame building was far rougher than an aristocratic home yet far more comfortable than the sod or log houses of Dakota settlers. From 1921 caretakers ran it as a boarding house, and it suffered theft and neglect before North Dakota received it in 1936.
