Magheraghanrush Court Tomb was built c. 3000 BC. It may have first been a simple construction with U-shaped court; the east part was added later.
Local legend has it as a Giant's Grave or Druid's Altar, or the burial site of Eógan Bél (d. AD 542), King of Connacht, although the Middle Irish poem Caithréim Cellaig says he was buried on Knocknarea and reburied on an island in Lough Gill.
The tomb is very large, 30 m long. The court is oval and located in the centre with two chambers at one end and a single chamber at the other, giving it the appearance of a man from above. The central court is not a perfect oval but is crooked in the middle, indicating that there was originally one court cairn which was then added to.
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.
