Carcassonne Cathedral was built in the 13th century as a parish church, dedicated to Saint Michael. Following war damage in the 14th century it was rebuilt as a fortified church. In 1803 St. Michael's was elevated to cathedral status, replacing the earlier cathedral dedicated to Saints Nazarius and Celsus, now the Basilica of St. Nazaire and St. Celse.
The cathedral plan is characterised by its relative simplicity. It forms a single nave with a 20 metre high vault, lined with several lateral chapels. The chior screen has retained its 14th century stained glass. The sober façade has a single decorative feature in the form of a large rosette 8 meters in diameter, and the adjoining bell tower is relatively massive.
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.
