Kasteel Wittem, now a national listed monument, was probably built in the 11th century. The oldest records in which the castle is mentioned date from 1125. The next century the castle was owned by the knights of Julémont. They started to call themselves Lords of Wittem. A title that was assumed by later owners. During their ownership in 1286, Reinoud, Count of Gelre, tried in vain to take the castle by surprise. In the early 15th century the castle was considerably enlarged until it consisted of a powerful stronghold with 7 towers and two moats spanned by bridges. Every bridge was equipped with a gate building.
The following successive owners of the castle were the knights of the Van Scavendriesch family and the Van Cosselaer family. In 1466 the castle was sold to Diederik van Pallant. In 1520 Emperor Charles V elevated Wittem to a Barony, probably as a reward for his sojourn at the castle on his journey to Aix-la-Chapelle for his coronation.
At the beginning of the 80-Years War Wittem Castle was confiscated by the Spanish under the Duke of Alva. His troops were expelled, in 1568, by the mercenary troops of William the Silent, Prince of Orange. Next William left to Maastricht to also free that city from the Spanish. When he didn't succeed he returned to Wittem Castle only to find it again taken by Spanish troops. Yet again he drove them out. In 1569 the Spanish returned again after which they destroyed the castle.
The castle was restored and enlarged in 1611, with compensation money for the war damages, by the Van Pallant family. In 1639 ownership of the castle transferred to the Counts of Waldeck Pyrmont. In 1678 they again had to restore the damage done to the castle, this time by French troops garrisoned in Maastricht.
In 1714 Count Ferdinand von Plettenberg became the last noble owner of the castle. When he came to the castle it already was in a dilapidated state. In 1794, after the French Revolution, the ruinous castle was taken from the count and sold to Simon Merckenbach. His family restored the castle to its present state and made it habitable again. In 1958 the castle was sold and is since being used as a hotel-restaurant.
The present building forms just a small part of the medieval castle. It consists of a round corner tower with two wings. In the farm buildings belonging to the castle are also parts of remaining medieval walls.
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.
