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.
