The Rafal Rubí navetas are two tombs of the same type as the Naveta des Tudons, but these are smaller and are unusual in that they are very close to one another. They are group burials with a perforated stone slab at the entrance to the inner chamber, which is split into two levels.
Of the two navetas, the east one is in better condition, as the front was restored in the late 1960s, when an archaeological dig was also carried out during which burial goods were found, including pottery items, rhomboid-shaped bronze pendants and part of a torc. The west naveta was excavated in 1977 and the human remains found in the upper chamber were dated to 904 B.C.The items found are on display in the Museum of Menorca.
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.
