The Slack is a small coastal river, which flows into the sea, near Fort Ambleteuse.
Although modest today, the Slack was much more imposing in the past, when the gravel was mined near the fort. At the time of the Camp de Boulogne, between 1803 and 1805, Napoleon had even thought of bringing his fleet here. Suffice to say that the Slack was something else!

Fort d'Ambleteuse

Highlight • Historical Site

This fort is the only one left of the seven that defended the coast of Boulogne.
In 169, the English king James II, chased away by his subjects, came ashore in the already silted up harbour. When Napoleon planned an invasion of England, part of his fleet was located here. From the beach you have a view of the entrance to the port of Boulogne and in clear weather even of the English cliffs.
