Royers Lock, Maritime lock in Port of Antwerp, Belgium

Royers Lock connects the Schelde River to the Albert Canal using a system of three large steel sliding gates that operate on rails. Two bridges span across the gate system, allowing both ships and road traffic to move through simultaneously.

The lock was built between 1893 and 1908 to handle the growing ship traffic in the port. Its construction reflected the port's increasing importance as an international trading center.

The lock is named after Gustaaf Royers (1848–1923), head of Antwerp's city works department. The carved stone inscription "Royerssluis 1907" from the demolished inner towers is preserved at the south side, where a signal light now stands. The lock is the busiest in Antwerp, often handling 24 to 27 lockages per 24 hours.

The lock complex is accessible from the harbor area, and the two bridges offer good vantage points to watch the gates operate. Walking along the canal promenade allows visitors to experience the facility from different angles.

The middle gate, 100 metres from the lower gate, was meant to shorten turnaround times, but the gain proved so small that it was taken out of service. The lock's gates were the first in the world driven by electric engines, and each steel caisson is ballasted with water to close and deballasted to open.
