Gloslunde Church was built in the 13th century. Built of red brick but now whitewashed, the church consists of a Romanesque chancel and nave and a Gothic porch and sacristy. A 14th-century timber bell tower stands close to the church's northwest corner. There are two small Romanesque windows on the chancel gable, now both bricked up. The east gable is also decorated with a round-arch frieze. The original flat wooden ceiling was replaced in the Gothic period with a star-shaped vault in the chancel and two cross-vaults in the nave.
In a Neo-Gothic frame, the altarpiece contains a painting of Christ in the Garden of Gethsemane by Frederik Christian Lund in 1872. An earlier catechism altarpiece from 1581 in the Renaissance style can be seen in the porch with text from Martin Luther's catechism in its six panels. The pulpit (c. 1590), also in the Renaissance style, presents the paintings of the four Evangelists set in rural scenes with hills and hedges.
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.
