Details
A historic canal structure of great importance to the transportation, structural, cultural and social fabric of Frederick County, the Village of Lander, the C&O Canal, the State of Maryland and our nation. The Catoctin Aqueduct site is where, in 1832, two arch rivals, the C&O Canal and B&O Railroad, first competed to concurrently cross at the same location a major tributary of the Potomac River, Catoctin Creek. It's one of 11 stone aqueducts on the 184-mile long C&O canal.
