Medieval Town of Dubrovnik is medieval fortress in the area of Višnjica, Ilijaš municipality, Bosnia and Herzegovina. Although there are no precise data on the origin of the city, it is assumed that it was built in the 13th century because it was first mentioned in the Dubrovnik archives, on July 11, 1404.
It is believed that the town was named after the medieval merchants from Dubrovnik who came in that period with the approval of the Bosnian king to exploit the mines of lead, zinc, gold and other precious materials.
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.
