The Tavna Monastery is a Serbian Orthodox monastery located south of the city of Bijeljina in north-eastern Republika Srpska, Bosnia and Herzegovina. The date of its foundation is unknown.
The chronicles of monasteries Tronoša and Peć say it was built by King Stefan Dragutin's sons Vladislav and Urošica. The present monastery church is built in the same place as the original one.
Tavna was damaged in the first years of Ottoman rule, but was restored by the people. This was not the only time the monastery was damaged. It was damaged many times during the Ottoman period and also during World War II. Between 1941-45 Tavna was bombed by the Nazi-affiliated Croat Ustashe but was reconstructed after the war.
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.
