The parish of San Vittore (St. Victor) is mentioned for the first time in the papal bull dated 5th April 1145 with which pope Eugene III took the canons of Saint-Gilles di Verrès under his protection. The parish church of San Vittore is rectangular in shape and has a single nave. The current church dates back to the end of the 15th century or the beginning of the 16th century and was consecrated in 1521. Its construction was financed by the counts of Challant, whose coat of arms may be observed on a keystone above a buttress.
The facade was rebuilt in 1670 and has a portico to protect the entrance. The seventeenth century portal in cut and sculpted stone is noteworthy and on the inside, the baroque altars in painted and gilded carved wood, are also interesting. The walnut stalls of the choir may be dated back to the end of the 17th century and bear the coats of arms of many of the noble families from the parish. With the new direction of the church beginning from the seventeenth century, the bell tower came to find itself behind the apse. Having collapsed in 1755, it was rebuilt in 1762 but it appears to have kept its medieval typology in the lower section.
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.
