Senez Cathedral formerly the seat of the Bishopric of Senez, abolished under the Concordat of 1801, when its territory was added to the Diocese of Digne.
The present Romanesque church stands on the site of several older cathedral buildings, but itself dates from the 12th-13th centuries. Construction started in 1176 and the cathedral was consecrated on 22 October 1246.
It suffered severely in the French Wars of Religion and its belltower was destroyed by Protestants. It was rebuilt in the 17th century.
It is particularly known for its church furnishings. The tapestries (seven by Aubusson, end of the 17th century, and one by Audemar of Enghien, end of the 16th century) were presented by Monseigneur de Ruffo Bonneval (bishop of Senez 1783–1784) to mark the completion of the restoration. Napoleon I passed through Senez on 3 March 1815 and greatly admired them. The church's choir stalls, lectern and altar, of the 17th and 18th centuries, are also particularly fine. It has two altarpieces of carved and gilded wood, also from the 17th century.
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.
