Brunegg castle was built on a hill at the edge of the Jura mountains in the 13th century. This castle was probably built, together with near Wildegg castle, as part of the Habsburg border defenses. The castle was occupied by Habsburg knights, including Schenken von Brunegg and Gessler von Meienberg. In 1415 the castle was besieged by Bernese troops, but they lifted siege after a counterattack. However, Bern conquered the Aargau, and awarded the fief to the Segenser or Segesser family.
Between 1538-1798, the castle was subordinate to the Governor of Lenzburg. In 1815 it became the property of the Hünerwadel family of Lenzburg. The current owners of the castle, the von Salis family, inherited the castle through marriage from the Hünerwadels. For hundreds of years, the castle was poorly maintained, and in the 17th Century it was heavily damaged twice through storm and tempest. In 1805-06, the keep and out buildings were repaired and the roof was rebuilt.
The village of Brunegg owes its name and existence to the castle. Initially it belonged to the personal land of the Habsburgs. In the 14th Century, they granted the rights to low justice into the hands of the castle owners. Bern placed in the court of Othmarsingen in the Lenzburg district. In the 19th century it was part of the Brugg district though since 1840 it has been in the Lenzburg district.
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.
