Carrowmore is a large group of megalithic monuments on the Coolera Peninsula to the west of Sligo, Ireland. They were built in the 4th millennium BC, during the Neolithic Age. There are thirty surviving tombs, making Carrowmore one of the largest clusters of megalithic tombs in Ireland.
The cemetery is accessible by foot. Explore the tombs and stop off at the restored cottage to see a small exhibition relating to the site. Check out the boulder circles with central dolmens and rudimentary passages that are among the earliest megalithic chambers built in Ireland. Don't forget to wear shoes suitable for walking on uneven terrain.
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.
