Origin and history

The ruins of the old lock of Mardyck, located in Dunkirk, constitute a listed historical monument. This site, whose exact origin is not specified in the available sources, bears witness to an industrial or maritime heritage linked to local history. Its classification by decree of 18 June 1930 emphasizes its architectural or historical importance, although details of its construction or its initial use remain unknown.

Locks, in general, played a key role in the management of waterways, facilitating the transport of goods and people. In a region such as the Hauts-de-France, marked by strong port and commercial activity, these infrastructures were essential for economic development. Their abandonment or ruin often reflects the evolution of techniques or needs, but also the preservation of a technical and cultural heritage.
