Slusen, Lock system in South Harbour, Copenhagen, Denmark
Slusen is a lock system between Zealand and Amager islands that regulates water levels in Copenhagen Harbour using granite embankments. The structure manages water flow between the two islands through gates and chambers designed for precise control.
The lock was built between 1901 and 1903 to solve navigation problems caused by strong currents in the harbor. This construction was essential for ship safety as vessels needed to pass through the difficult passage.
The lock was designed by architect Vilhelm Dahlerup, whose buildings shape the harbor's character today. The keeper's house and engine room on an artificial island show the craftsmanship of early 1900s architecture.
The lock is accessible from the outside and offers good views of harbor activities. After its 2004 renovation, the structure operates reliably, and visitors can watch the lock in action from several vantage points.
Nearby sits an unusual houseboat community called Husbådskolonien København, established in 1987. This floating neighborhood represents a distinctive way of living on the water near the working harbor.
