St. John's Church was probably built in the first third of the 14th century as a three-nave basilica. The church was damaged in the Russian- Livonian War in the 16th century; lightning has set its spire on fire several times. Some parts of the church were destroyed in the Great Nordic War in 1708.
In the end of 19th century external walls of St. John's Church were cleaned of limewash, the original shape of the choir windows was restored and new external figures were made of instead of the destroyed ones. The building was reconstructed in the Neo-classicism style in 1930’s. During World War II, the church caught fire. The damage was so extensive that an unknown and rich interior decoration was discovered the beneath the destroyed plaster sheet. There have been over a thousand sculptures in the internal and external walls of the construction. There is no other brick church decorated with so much terracotta plastic in Europe.
There are fifteen figures in the triple arch niches of the fronton which represent Judgement Day. On the facade and two sides of the tower there are other figures since the tower's frieze consisting of quaternion foils with a human head continuing in each quaternor foil on the sides of the longitudinal building as well. There are friezes and niches decorated with sculptures in the interior as well.
However, the western wall, with numerous niches with sculptures and pseudotriforium located above the arcades in the niches of which there are figures sitting on a throne, deserves special attention. In the eastern wall, above the triumphal arch, there is a large terracotta group: Christ on a cross and Mary and John beneath the cross.

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.
