Havré Castle is a ruined water castle in the village of Havré in the town of Mons. The origins of the castle can be only traced back to the year 1226, even the counts of Flanders and Hainaut have had control over Havré since the 11th century. In 1255 Ida of Mons was married to Engelbert d'Enghien. Their descendants keep Havré Castle to the year 1423. Then Gérard d'Enghien passes the Castle on to Christophe d'Harcourt. Through marriage, the castle came into the possession of the families Dunan, Longeville and Croy.
In 1518 Philip II de Croÿ commander of Emperor Charles V, became the owner of the castle. By 1537 he was in charge of County of Hainault as grand baliff and governor. Phillipe married on 9 August 1548 Anna of Lorraine as his second wife, a daughter of the Duke Anton II of Lorraine. He died before the birth of his son Charles-Philippe. Wounded by a musket Charles-Philippe was treated by Ambroise Paré at Castle Havré, who was the first surgeon to French King Charles IX and a prominent surgeon of his time.
In 1578, the castle underwent its roughest period with siege by the armies of Don Juan de Austria and the Duke of Anjou. The castle was kept without much damage. Unfortunately, in 1579 a fire was fierce and devastating burning the castle to the walls.
During the seventeenth century it is Charles Alexander, Duke of Croy, who would restore the castle and make it one of the most magnificent castles of pleasure in Belgium, where many royals and famous artists of the time liked to stay.
Shortly after the French invasion of 1792, it was quickly sold as national property. Despite its acquisition in 1807 by the family of Croy, the castle was gradually abandoned.
Finally at the beginning of the twentieth century what was left, the castle due to negligence from 1930 transformed into ruins.
References: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.
