The Proserpina Dam is a Roman gravity dam in Mérida, Spain, dating to the 1st or 2nd century AD. It was built as part of the infrastructure which supplied the city of Emerita Augusta with water.
After the fall of the Roman Empire, the Milagros aqueduct leading to the city fell into decay, but the earth dam with retaining wall is still in use.
It is also part of the Archaeological Ensemble of Mérida, an UNESCO World Heritage Site since 1993.
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.
