The slaughterhouse was built in the town which the Marquis founded and named for his wife, Medora Marie Von Hoffman.

For three years the small town bustled, but in 1886 the operation collapsed due to drought, competition from meat packers back east,[4] and the Marquis' own lack of business experience, and the plant was abandoned.

The Marquis and his family returned to Europe, but left behind a small town rife with the flavor and romanticism of the American Old West.

The Chateau de Mores is currently operated as a museum by the State Historical Society of North Dakota.

While rough by aristocratic standards it was considerably more luxurious than most contemporary homes built by Dakota settlers, which were mostly constructed of sod or logs.
