Plassenburg is one of the most impressive castles in Germany and a symbol of the Kulmbach. It was first mentioned in 1135. The Plassenberg family were ministerial of the counts of Andechs (later the dukes of Andechs-Meranien) and used as their seat the Plassenburg. The House of Guttenberg, a prominent Franconian noble family, traces its origins back to 1149 with a Gundeloh v. Plassenberg. The name Guttenberg is derived from Guttenberg and was adopted by a Heinrich von Blassenberg around 1310. From 1340, the Hohenzollerns governed from Plassenburg castle their territories in Franconia till 1604. The Plassenburg was fortress and residence for the Hohenzollerns.
The castle was destroyed in 1554 at the end of the second Margravian war (1552–1554) of margrave Albert Alcibiades. The Plassenburg was later rebuilt by the architect Caspar Vischer as an impressive stronghold and as a huge palace. In 1792, Margrave Alexander sold the Plassenburg to his cousin, the King of Prussia. A combined Bavarian and French army under the command of Jérôme Bonaparte, brother of Napoleon, besieged the Plassenburg in 1806. In 1810, Kulmbach became Bavarian and the castle was used as a prison and as a military hospital. During the second world war, the Organisation Todt used the Plassenburg as a training camp and recreation home. Today, it is a museum and a venue for cultural events.
It contains a significant collection of Prussian military artifacts and portraits.
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.
