Ballymote Castle is a large rectangular keepless castle, built around 1300. It is located in the townland of Carrownanty on the outskirts of Ballymote. It is the last of the Norman castles in Connacht. It was probably built in order to protect the newly won possessions of Richard Óg de Burgh, 2nd Earl of Ulster (also known as the Red Earl), in County Sligo, some distance from an earlier motte.
Ballymote castle is a large enclosure castle, the most symmetrical of all the Irish 'keepless' castles. It has many similarities with Beaumaris Castle, in Anglesey, Wales, built by King Edward I of England. The entrance, with a double towered gate, is in the north wall and had twin D-shaped towers. It has a gatehouse typical of the period, the outer portions of which have almost completely disappeared. The castle, however, remains an impressive structure. The interior measures about 30 square metres. There are three-quarter round towers at all four corners and also in the middle of the east and west walls. A postern gate, which was planned for the centre of the south wall, was never completed, probably because of the events of 1317, when the castle was lost to the O'Connors. A small square tower had protected this gate.
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.
