The Cathedral Church of the Nativity of the Theotokos is the largest Serbian Orthodox church in Sarajevo and one of the largest in the Balkans.
The cathedral is dedicated to the nativity of the Theotokos. It was erected at the request of the Orthodox parish of Sarajevo, with construction taking place between 1863 and 1868. The church is constructed as a three-section basilica inscribed in a cross-shaped plan, and has five domes. The domes are built on the beams; the central one is much larger than the other four side domes. The church is arched by round elements. The small gilded baroque-style belfry is built in front of the entrance. The interior walls are decorated by painted ornaments. In the lower zones of the walls the painted ornaments are simulating the marble stone construction look. Arches and vaults are decorated in ornaments only. In 1898, the Orthodox Metropolitan Palace was built near the cathedral.
The head master for construction was Andreja Damjanov, a man from the Damjanovi-Renzovski family of master builders, masons, painters, carpenters, and stonecutters from the village of Papradište, near Veles.
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.
