Schleuse Kannenburg, Navigation lock in Templin, Germany.

Schleuse Kannenburg is a lock at kilometre 3.60 of the Templiner Gewässer, in the far south-west of the Uckermark district within the town of Templin. The 1906 chamber had sloping walls faced with stone slabs on a timber sheet pile wall, brick heads partly clad in natural stone, and wooden mitre gates. Its usable length was 41.50 metres, width 5.30 metres, with a mean fall of 1.41 metres.

The original lock was built in 1795 to help vessels cross different water levels in this area. A major reconstruction took place in 1906 to better accommodate increasing boat traffic.

The lock serves as a meeting point for canoeists and boaters navigating between the region's many lakes. People gather here to move their vessels through the interconnected waterways that link Brandenburg's water system.

Boaters can operate the lock themselves, making passage straightforward and independent. Visit during less busy times for quicker passage, especially during warmer months when water traffic increases.

The old lock chamber, closed since November 2017 because its wooden sheet-pile walls could no longer be certified as safe, was rebuilt on the same spot to its previous dimensions. The city of Templin handled planning and construction for the federal government under a public-public partnership, with the federation covering the roughly 15 million euro cost.
