Église Saint-Maurice (Church of Saint Maurice) is notable for its medieval tower and for being one of the earliest examples of Gothic Revival architecture in Alsace.
The church was first mentioned in 1165. The basis of the tower is Romanesque (late 12th-century). It is decorated with reliefs on the outside and with frescos on the inside. The upper part of the tower is Gothic and dates from the end of the 15th century. The rest of the church was rebuilt according to plans (1843, 1844) by the architect Charles Morin (1810–1897), and inaugurated in 1848. In 1888, the nave was covered with a wooden barrel vault.
The pipe organ is a 1762 work by Johann Andreas Silbermann. It was moved into this church from Old Saint Peter's Church, Strasbourg, in 1865.
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.
