Happy Canal Fact Friday and #PreservationMonth! In March, City staff collaborated with Carr Properties to salvage and relocate 144 Alexandria Canal stones uncovered during construction at 425 Montgomery Street, for eventual re-use within a waterfront park. The canal stones have been temporarily relocated to the adjacent Montgomery Park for future integration into the construction effort associated with the Waterfront Flood Mitigation Project. You can see the stones lining the west side of Montgomery Park. Learn more about the project at alexandriava.gov/go/6378. ... See MoreSee Less

"The C&O Canal aqueducts are “water bridges” that carried canal boats over the creeks and rivers that flow into the Potomac River. Built from 1829 to 1833, the Monocacy Aqueduct is the third of twelve such “works of art” on the canal. With just one glace, visitors are struck with the magnitude of this marvelous seven arched structure. The glistening white and pink quartz sandstone structure is the longest aqueduct along the C&O Canal measuring in at 516 feet. At the time of the Civil War, during the Maryland Campaign of 1862, the Monocacy Aqueduct was nearly destroyed by Confederate General D.H. Hill. However, concerned Lockkeeper Thomas Walter persuaded the Confederate troops that destroying Lock 27 would be far more impactful in their pursuit.

The Monocacy Aqueduct was the second of eleven aqueducts constructed and was known as Aqueduct No. 2. The stones are quartzite and came from the property of Joseph Johnson. There were two quarries opened on his property including the white and red quarries. In addition to destroying lock 27 Thomas Walter persuaded the Confederates to destroy the Little Monocacy River culvert. Because of his actions, Walter was fired as lock tender and was replaced by Allen Benson. Walter became a boatman on the canal. In 1831 Walter had the contract to build culvert number 44 that later was converted into an aqueduct after the culvert washed out. This aqueduct became known as the Trunk Aqueduct.
