Poiters Cathedral construction began in 1162 by Henry II of England and Eleanor of Aquitaine on the ruins of a Roman basilica, and work was well advanced by the end of the 12th century. It is the largest medieval monument in the city of Poitiers.
It is built in the Romanesque and Early Gothic styles, the latter predominating. It consists of three naves almost equal in height and width, all three of which decrease towards the west, thus enhancing the perspective. Its length is 308 ft., and the keystone of the central vaulted roof is 89 ft. above the pavement. There is no apse, and the exterior generally has a heavy appearance. The principal front, which is broad relative to its height, has unfinished side-towers 105 and 110 ft. tall, begun in the 13th century.
Most of the windows of the choir and the transepts preserve their stained glass of the 12th and 13th centuries; the end window, which is certainly the first in the order of time, contains the figures of Henry II and Eleanor. The choir stalls, carved between 1235 and 1257, are among the oldest in France.
On the night of 25 December 1681 the organ was destroyed by fire. It was not until 1770-78 that a campaign was launched to build a replacement. François-Henri Clicquot, at that time the leading organ-builder in France, was appointed to undertake the work, but died in Pentecost 1790 before completing the work. His son, Claude-François Clicquot, finished the job, handing it over for presentation in March 1791. The instrument is a beautiful example of eighteenth-century organ design, and is still largely intact.
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.
