Saint-Génis-des-Fontaines Benedictine abbey is recorded for the first time in 819, in a document mentioning its abbot, Sentimir. Plundered and destroyed, it was rebuilt by order of King Lothair of France in 981. Later it came under the protection of the Counts of Roussillon and later of the Kings of Aragon. The abbey church was enlarged and re-consecrated in 1153. In the 13th century it gained a marble cloister on the north-eastern side. Subsequently the abbey declined, and in 1507 was united with Montserrat Abbey.
During the French Revolution, the monks were expelled and the complex divided between several owners. The church was reopened to worship in 1846, as the village's parish church dedicated to Saint Michael. The cloister, which had been dismantled and sold, was bought back and re-installed in its original location in the 1980s.
The abbey church was most likely built at the same time as the original monastery, in the 8th century. Of the original church there remain some of the foundation structures, which show its plan to have included a main apse and two deep side apses, with a long transept.
The 1153 enlargement, with the addition of the vaulted ceiling over the transept and nave, led to the reconstruction of the walls in order to support the additional weight of the roof vaults. The ceilings of the apses were also modified and decorated with frescoes, of which only a few traces remain today. The church kept the Latin Cross plan typical of Romanesque architecture, with a nave, transept and three apses. In the 17th century the church was enriched with Baroque altars.
The exterior has two bell towers from different ages. The larger one is located next to the transept and nave. The façade has several Romanesque sculptures and tombstones of monks and local notables. The main portal has an architrave with bas-reliefs commissioned by abbot Guillaume and realized in 1019-1020 in white marble from Céret. In the middle is portrayed Christ in majesty in a mandorla, supported by two archangels and flanked by two groups of three figures under the arcades.
The cloister was built in the 13th century, and was already completed in 1271. It has been supposed that a cloister existed here before, which would be the one depicted near the figures in the portal architrave, but no traces of it remain. The capitals supporting the 13th century cloister are in late Romanesque style. It has been suggested that they could originally have been painted.
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.
