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.

Built in 1815, little more than the walls remain of this saw and grist mill. Don't let that put you off though, peek inside you can find examples of mill machinery which were added in the 1980s to show how it used to work.
