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.

Hardelot Castle

Highlight • Castle

This neo-Gothic mansion is located in front of the lake of mirrors. It was built in the 19th century by Sir John Hare, who drew inspiration from Windsor Castle but retained the remains of the 13th century fortification. In 2009 it was restored by the department, furnished and decorated in Victorian and Napoleon III style. Today, visitors are told about the history of the castle and what the Franco-English "accord cordial" is, as well as in a more general way the particular relations between these two countries.

The Castle of Colembert is located in the village of Colembert, in the Pas-de-Calais department, France. The land of Colembert was made a marquisate by Louis XIV in favor of Gabriel de Maulde.

The current owner is Baron Olivier Law de Lauriston-Boubers, descendant of Louis-Charles de Sainte-Aldegonde .

An old fortress from the 13th century. A nice park, but other than that there is not much to see.

The castle has been preserved in its original plans. It was built in the Middle Ages (13th and 15th centuries). It is an example of a fortified castle from the plains of Northern Europe. A walk along the “Moats” and an interior visit to the chapel, the vaulted cellars and the floors of the keep are recommended. Enjoy a distant past in the present.
