The castle stands on the site of a fortress originally built by the Counts of Boulogne to defend the coastline.
Sir John Whitley, the builder of the current castle, was a British industrialist who developed the nearby resort of Hardelot-Plage.
The interior contains an extensive collection of historical archives detailing the 'Entente Cordiale' between France and the United Kingdom.
The castle is surrounded by the 'Marais de Condette', a protected nature reserve featuring a diverse range of local flora and fauna.
The Elizabethan theater on the estate grounds is designed entirely from wood, mimicking the style of 16th-century English playhouses.
The moat surrounding the castle is fed by the natural springs of the nearby Source river.
Hardelot Castle is a 19th-century Neo-Tudor manor built upon the foundations of a 12th-century medieval fortress. It is situated within the Condette forest, surrounded by a restored moat and botanical gardens. The site serves as the Centre for Cultural Relations between France and Britain, hosting exhibitions and performances throughout the year. The current structure was commissioned by Sir John Whitley, who transformed the ruins into a residential estate in the mid-1800s. The castle architecture features distinctive red brickwork, crenelated towers, and Gothic revival interiors. Visitors can explore the preserved rooms that document the history of cross-channel diplomatic relations. The grounds include an Elizabethan-style theater located within the parkland. The castle underwent a significant restoration project completed in 2009 to stabilize the masonry and modernize interior spaces for public use.
