Santa María Jus del Castillo Church was built in the 12th century on the site of a synagogue, since this was then the Jewish quarter of the city. Its original name was Iglesia de Santa María y de Todos los Santos. It was used as a church until the 17th century. Today it is used as an Interpretation Center of the Romanesque and the Camino de Santiago. It was declared a Site of Cultural Interest.
It is a church with a single nave. The apse and the central body of the church are Romanesque, but the façade and tower are from the Baroque period.
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.
