Lock 23, Canal lock in Darnestown, United States.
Lock 23 is a canal lock made of red sandstone from Seneca Quarry, located on the Chesapeake & Ohio Canal in Darnestown. The structure sits at an elevation of 54 meters above sea level and remains a visible part of the historic water system.
The lock was built as a critical point in the canal's water management system, supported by Dam No. 2 during operations. Between 1938 and 1942, the Civilian Conservation Corps performed restoration work to maintain water levels from this location downstream to Georgetown.
The lock got its alternate name, Violettes Lock, from Alfred Violet, the last locktender who worked here. You can still sense the connection between the structure and the people who operated it daily.
The site provides parking areas, canoe and kayak launching ramps, and restroom facilities for visitors. Wear comfortable walking shoes to explore the surrounding paths and view the structure from different angles.
The red sandstone used in the lock came from the nearby Seneca Quarry, making it a notable example of using local materials for construction. This choice of sourcing stone from the area helped the structure maintain its integrity over the years.
