Boudewijnsluis

Boudewijnsluis is a large navigation lock in Antwerp's port that allows seagoing vessels to move between the North Sea and inland waterways. The facility features massive gates and chambers that regulate water levels to safely accommodate ships of different sizes.

The lock opened in 1955 as a response to the growing need for larger vessels in Antwerp's port operations. It became a key infrastructure that helped establish the port as one of Europe's most important shipping hubs.

The lock stands as a working monument to Antwerp's maritime identity and the central role of shipping in the city's economy. Visitors can watch from the banks as massive vessels pass through the narrow passage, gaining insight into how essential this facility remains for daily port operations.

Visitors can watch the lock from the riverside, especially when vessels pass through, though there is no public access to the facility itself. The best times to observe activity are early morning or afternoon when vessel traffic is heaviest.

During the post-war decades, this lock experienced peak traffic volumes and was once the busiest waterway crossing in the entire port. Today it handles fewer vessels, but remains a vital connection between ocean shipping and inland navigation networks.
