The Castello di Caprarica is a castle in the municipality of Tricase. The building of the fortress was probably a consequence of the climate of fear that spread after the Turkish conquest of Otranto in 1480 and the subsequent Turkish raids. The fortress has a rectangular plan and was once surrounded by a moat. The 6-7 meters high and 1.4 meters thick walls were made from irregularly shaped blocks of brown Carparo - limestone constructed and have a robust floor division. At the corners there are round towers with sloping walls and small consoles that support the upper frames. The strict entrance portal is protected by a triple machicule.
Numerous rooms are arranged inside: four rooms on the ground floor, six on the upper floor, storage rooms and kitchens. Within the walls there is also a garden and a cistern for the water supply. At the beginning of the 20th century, traces of frescoes and figural niches of the small, inner chapel , which is dedicated to Saint John the Baptist , but is sometimes also called Christopher Chapel , could be identified, presumably through an empty room with ogive vaults , supported by pillars leaning against the wall. The fortress was used as a farm at the end of the 19th century.
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.
