Bergues is located about ten kilometers from the coast, but a small detour is certainly worthwile. It lies on the banks of the river Aa, which comes from Gravelines and flows into the North Sea. Like Gravelines, Bergues is a Vauban fortress, which is still completely walled.
The main attraction of Bergues is its belfry. It is fully erected in brick. The current version only dates from 1960, after the previous one was blown up by the Germans in 1944. Thanks to the channel that through the city, it is sometimes called the 'Bruges of Northern France'.
