Building located at Condette, the castle of Hardelot is a manor house remodeled in the 19th century in the neo Tudor style, on foundations from the first half of the 13th century.
The first castle at this site was built in the 12th century by the Counts of Boulogne. The curtain walls date back to that time. The present castle was built by Philip I, Count of Boulogne and son of Philip II of France, in 1222. He also built Boulogne-sur-Mer Castle to a rather similiar plan; a more or less circular castle with projecting circular towers but no keep.
In 1848 Hardelot Castle was bought by the Englishman Sir John Hare. He rebuilt one of the best remaining towers into a Tudor-style mansion. Large receptions were given here and the writer Charles Dickens, a friend of Hare, often visited the castle.
Located on the edge of the regional nature reserve of the Condette marsh, near the forest and the dunes of Ecault, it now houses the Cultural Center of the Entente Cordiale, managed by the Department of Pas-de-Calais. The rooms of the castle are fully furnished and retrace the tumultuous relations between France and Great Britain.
Towering 52 meters above the sea, Bengtskär lighthouse is the tallest one in Scandinavia. The building started in in 1905 after the shipwreck of S/S Helsingfors and was completed in 1906. The lighthouse was designed by architect Florentin Granholm. On December a special petrol lantern, designed and built in Paris, was brought to Bengtskär and installed atop the tower.
German fleet bombarded Bengstkär in the First World War in 1914. Since the Gulf of Finland was heavily mined, it was not until 1919 that the surrounding seas were declared safe for shipping, that the light was lit again.
After the war the military value of Bengtskär increased as part of the defence system of independent Finland. In Second World War (1941) Soviet Union made a suprise attack to island. After a bloody battle, the small Finnish garrison emerged victorious. Intermittent repairs to the facility continued during the post-war period.
