Kizichesky Vvedensky Monastery is a small male monastery in Kazan. It was founded in 1691 by Adrian—the Moscow Patriarch, who until 1690 were the Kazan Bishop. The name Kazichesky means Holy Martyrs of Cyzicus. The monastery was devoted to the martyrs because parts of their relics were brought to the monastery—according to the wishes of Adrian. In the 1690s Vvedensky Cathedral and Vladimirskaya Church were built. Vvedensky Cathedral was destroyed during the Soviet epoch. Ilya Andreevich Tolstoy (the grandfather of Lev Tolstoy) is buried in the monastery.
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.
