Built in 1296, Ehrenberg Castle offers everything you would expect from a medieval castle, defensive walls, tall towers and a lot of history. The gothic castle complex was home to emperors and kings, princes and tzars.
Ehrenberg was in the center of wartime battles several times. In 1546, the Protestant Schmalkalden occupied the fortress. In 1552, it was taken by the Elector Moritz of Saxony. In 1632 the Swedes stopped in front of its walls. In 1703, Ehrenberg fell into the hands of the Bavarians during the War of the Spanish Succession. From 1716 to 1717, Ehrenberg became the exile of Russian Tsarevich Alexei, who fled from his father, Tsar Peter the Great. Even in the Napoleonic Wars, it played a role. Beginning in 1971, Fridolin Schennach from Reutte took over the condemned ruin and initiated a rescue operation with numerous other idealists.
In 2014, the world's longest pedestrian suspension bridge was completed between the Ehrenberg Castle ruins and Fort Claudia, spanning the strategically important pass that these two structures were in part meant to guard. The length of the bridge 403 meters, with a height of 110 meters.
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.
