Fort Wohlgemuth was built between 1850 and 1851. It is called Wohlgemuth because it is dedicated to an Austrian general, who fought in the battles of the year 1848. It has been built by using local stones and it has got fried brick archivolts.
After the annexation of Veneto to Italy, it became property of the Italians. Since then it has been modified and, in fact, a new battery named “low Rivoli” was built in 1884. It consists of a large square enclosed by ramparts.
Currently the fort hosts a World War I Museum.
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.
