Built in 1837 by the Seneca Sandstone Company, this mill was created to process the distinctive red sandstone quarried nearby. Today, the ruins, easily spotted by their red sandstone walls, are accessible via the C&O Canal towpath and are especially visible during the winter months when vegetation is dormant.

It was named after the Swain family and John Swain, who helped build the canal, and Jesse Swain, the lockkeeper. The family lived here until 2006.
