Just off the tow path of the C&O canal, there are the remains of a quarry and the ruins of one of the most important stone mills in the Washington, DC region. Join APT DC for a tour of the Seneca Sandstone Quarry and Mill to learn about the site and the infrastructure built to make it function.


Tour - Saturday, February 22, 10:00am-12:00pm: Joe Himali (NEW DATE)

We will explore the ruins of the Seneca Sandstone Mill and hike to the quarry itself and see the veins of stone that produced the blocks that were used in the construction of the Smithsonian Castle and many other important buildings in Washington, DC.

The tour includes a discussion of the checkered and tragic history of the C&O Canal including a visit to see Riley’s Lockhouse and the special lock it controlled, which is the only combination aqueduct and lock on the entire canal.

You will learn how this historic site is intricately intertwined with the history of Washington, DC, its powerful elites, the collapse of the Freedman’s Bank, along with other fascinating stories.

The tour is approximately 1.5 miles/2.4 km. The path may be slippery and uneven and requires outdoor gear. You will want to wear strong, waterproof shoes with good grip and clothes that can handle overgrown, dense foliage, brambles, and mud.

Finally, for anyone who wants to join, we will continue the conversation with Joe with lunch on your own at the nearby Rocklands Farm Winery.
