Gars Abbey was founded in 768 by the cleric Boso from Salzburg for Tassilo III, Duke of Bavaria. For centuries it belonged to the archbishopric of Salzburg. The Augustinian Canons erected the present monastery building after 1122. In 1128 Bishop Conrad I of Salzburg transferred the monastery to the Augustinian Canons.
In 1648 the Swedes pillaged and devastated the town and the monastery. Under Provost Athanasius Peitlhauser the monastery was rebuilt between 1657 and 1659. The monastery wings and the Church of the Assumption were renovated by Italian artists to their present form. The pilaster church was rebuilt after 1661, one of the first Baroque churches in the region. The painted cast stone Pieta on a side altar dates from 1430, and was formerly the main altar of the church. The monastery is interesting for the relics of the martyr Felix. Ceiling paintings and an altar show the importance of this saint to the monastery.
In 1803 the Augustinian Canons were expelled as part of the Bavarian secularization program. The buildings and inventory were sold to private individuals. In 1855 the Redemptorists showed an interest in Gars Monastery, and in 1858 they formally re-opened the monastery. Between 1873 and 1894 under the Kulturkampf only three fathers and brothers were allowed to remain. After the monastery was restored in 1894 the first missionaries were sent to Brazil.
As of 2013 the monastery housed about 16 brothers and 13 priests. The brothers follow various professions including work as bakers, butchers, gardeners, carpenters and tailors. The Fathers work as ward missionaries, helping in the surrounding communities and in education. The monastery has a plant nursery that is well known in the region.
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.
