A monastic cell existed in Dorfbeuern as early as 736 or thereabouts, referred to in the Aachen Monastery Register in 817. After the Hungarian wars, reconstruction began in 977 with an endowment from Emperor Otto II. More times of crisis came upon the abbey with the fire of 1346, mismanagement of the prebendal income and the effects of the Reformation.
From the 17th century however Michaelbeuern began a long period of prosperity, which led to ambitious building works, for example the Baroque high altar of 1691 in the abbey church, by Meinrad Guggenbichler and Johann Michael Rottmayr. At this time more than twenty-five monks of Michaelbeuern gained their doctorates at the Benedictine University of Salzburg. The community also took on many pastoral responsibilities in the surrounding parishes. During the National Socialist period the monks were expelled, but returned after World War II. The abbey church, re-romanised, was re-dedicated in 1950.
The abbey today is a thriving Benedictine community, well known as an educational and cultural centre. The abbey runs a school and owns different business like a farm, a district heating plant, a biogas plant and a participation in a brewery (Augustiner Bräu Kloster Mülln).
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.
