Beauly Priory was a Valliscaulian monastic community. It was probably founded in 1230. It is not known for certain who the founder was, different sources giving Alexander II of Scotland, John Byset, and both. The French monks, along with Bisset (a nearby, recently settled landowner), had a strong enough French-speaking presence to give the location and the river the name beau lieu ('beautiful place') and have it pass into English. It is not the best documented abbey, and few of the priors of Beauly are known by name until the 14th century. It became Cistercian on April 16, 1510, after the suppression of the Valliscaulian Order by the Pope. The priory was gradually secularized, and ruled by a series of commendators. The priory's lands were given over to the bishop of Ross by royal charter on October 20, 1634. The ruins today are still extensive and are one of the main visitor attractions in Inverness-shire.
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.
