The Castle of Montevetrano is a medieval castle in the municipality of San Cipriano Picentino. The fortress originated from a Roman castrum of the 3rd century BC, built to control the Picentine populations who were relocated in the plain of Sele.
Between the 11th and 13th centuries, it was equipped with perimeter walls, with an entrance gate on the north side, and a cylindrical tower located inside the courtyard.
In 1867, the Carabinieri (Italian military police) used the castle to monitor the incursions of bandits. During World War II, the castle was occupied by the German army, who, thanks to its strategic position on the hill, could control the entire Sele Valley.
The castle's intact perimeter walls, four interior rooms, the three-level cylindrical tower, and two large cisterns have survived to this day.
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.
