Parksluizen, Maritime lock complex in Rotterdam, Netherlands
Parksluizen is a lock complex in Rotterdam connecting Coolhaven and Parkhaven harbors. The site contains a large lock for cargo vessels and a smaller one for pleasure boats, both built in the interwar period with concrete and brick construction.
The complex was built between 1931 and 1933 under the design of engineer C. Franx and architect Bastiaan van der Lecq. It emerged as part of Rotterdam's broader modernization of its harbor during that period.
The complex displays Dutch craftsmanship in its brick pillars and granite details along the Parkhaven Bridge. These architectural touches reflect how local builders approached their maritime infrastructure.
You can view the complex freely from the walkways and watch the locks operate from designated viewing areas. The best vantage point is the Parkhaven Bridge, where you can see both locks at once.
The smaller lock uses an innovative segment gate system that rotates around two fixed axes. This Burky closure mechanism was pioneering for its time and still operates with minimal effort today.
