Rathmannsdorfer Schleuse

The Rathmannsdorfer Schleuse is a canal lock in Altenholz that originally regulated water levels along the local waterway system. The remaining visible sections include stone walls, gate structures, and mechanical equipment that once controlled the movement of water and vessels.

This lock was built during the expansion of the German canal network in the 1800s to allow ships to move between sections at different water levels. Today it stands as a monument to the engineering work that shaped northern Germany's waterway system.

The lock takes its name from the nearby village and demonstrates construction methods typical of waterway projects from its era. Today, visitors can see how the stonework and mechanical systems reflect the practical knowledge of those who built and operated it.

The lock sits along a walking path that connects to Altenholz town center, with signage and informational panels at the site. Wear sturdy shoes since the paths around the lock can be uneven and damp, especially after rain.

The lock was partly destroyed, yet the remaining structures still display the original stonework and construction techniques from when it was built. These fragments offer a rare look at the material history of water infrastructure that visitors seldom encounter elsewhere.
