The church dedicated to Saint Symphorien near the Azay-le-Rideau château that is interesting for the number of architectural periods incorporated in its design. While the newest portion dates from 1603, the current façade incorporates an older 9th century façade in the Carolingian style. The original carved figures are still visible, though an added window destroyed part of the second row. The rest of the church is of a Romanesque style. It was built in 1518 and 1527.
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.
