Church of San Andrés is an impressive church built in stone in the 16th century. In the same building, several architectural styles are to be seen, from the gothic to the neoclassical and the renaissance. The most Gothic parts are the nearest to the towers. It's the only remaining part of the Gothic building over which the current building was erected. Picturesque columns and archs. In the other part of the church we can see the sacristy, in neoclassical style. In the middle part we can see the stylistic evolution in the building. In the 'crucero' part we can see a Renaissance style. The church has also a baroque and renaissance-style altarpiece. The 18th-century organ, of classical style, is still in use and used for concerts.
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.
