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.
