The Castle of Las Aguzaderas is located just outside the town of El Coronil. This curious castle, which appears to have been built by the Moors, was probably erected to defend a spring which was the water source for the fountain of Las Aguzaderas. This area was an intense war zone between the Moors and the Christians during hundreds of years and that made water a precious resource.
There is evidence that this castle was already here in the 14th century, and it is also known that there were modifications made to it in the 15th and 16th centuries.
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.
