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.

Photospot n°3: "The seals of Noirda":
For lovers of wild places, the Cran du Noirda is the perfect place. A small cove awaits you a stone's throw from Audresselles. It inaugurates a whole string of “notches” which will follow one another as follows: the Mademoiselle cran, the Chicken cran, the Egg cran which announce the cliffs of the Gris-Nez. Be careful, it is not uncommon to see a few seals and sea calves that come to enjoy the fish-filled waters of this part of the coast.
