The foundation of the castle on the island of Pantelleria can possibly traced back to the Arab or Byzantine period in Sicily, even if it is not attested with certainty before the 13th century.
The Castello Barbacane is located in the centre of Pantelleria town at the entrance of the old harbour and is accessed via a staircase from the Via Castello. It was a bulwark to protect the maritime trade of the island, facing the harbour on one side and walls lapped by the sea on the other side. Until just over a century ago, the castle was the predominant element of the walled city
The castle is well preserved and worth a visit.
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.
