San Michele Arcangelo is a romanesque-style church in the city of Potenza. A church at the site is first documented in 1178, however, floor mosaics, likely from the 5th century, uncovered in the church suggest that a late Roman structure was likely here before then. As was common for many Lombard churches, it was dedicated to St Michael Archangel. The stone portal has a sculpted relief of the Madonna and Child with some Franciscan Order symbols.
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.
