Stokkemarke Church dates from the mid-1200s. It was built in the Romanesque style with later additions in the Gothic period. The church was dedicated to St. Clement in 1396 although it was later associated with St. George, probably as a result of a panel from St Jørgens Hospital in Bregerup which hung in the church until 1878. A reliquary found in the high altar was a gift from Bishop Gisike of Odense (1286–1300), possibly a gift for the reconsecration of the altar on the completion of the apse which is just slightly older than the chancel. From the 14th century, the church was the property of the Crown but from the beginning of the 16th century, it was administered by Engelborg Manor on Nakskov Fjord. In 1687, it was transferred to the Bishop of Odense and later to Knuthenborg until it gained independence in 1912.
The church consists of a Late Romanesque chancel and nave and an apse, sacristy, porch and tower which were added during the Gothic period. It is built mainly of red brick with some fieldstone and with limestone trimmings. The chancel has corner lesenes and saw-tooth decorations. Both the north door and the former south door are now bricked up but traces of the original round Romanesque arches can still be seen. The tower is unusually large and almost as wide as the nave. The tower room has a pointed arch and a star-shaped vault. There is a small spire with a copper dome.
The chancel has a pointed arch and a vaulted Gothic ceiling in six segments. The original Romanesque windows in the nave were first converted into large Gothic windows with pointed arches before being replaced by today's smaller more modern windows which probably date from 1815. The cross on the altar dates from the end of the 15th century and was originally on the chancel arch. The Renaissance pulpit has four shell-shaped niches with figures of the Evangelists flanked by pilasters and covered with pointed arches.
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.
