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:
Roman Walls of Lugo are an exceptional architectural, archaeological and constructive legacy of Roman engineering, dating from the 3rd and 4th centuries AD. The Walls are built of internal and external stone facings of slate with some granite, with a core filling of a conglomerate of slate slabs and worked stone pieces from Roman buildings, interlocked with lime mortar.
Their total length of 2117 m in the shape of an oblong rectangle occupies an area of 1.68 ha. Their height varies between 8 and 10 m, with a width of 4.2 m, reaching 7 m in some specific points. The walls still contain 85 external towers, 10 gates (five of which are original and five that were opened in modern times), four staircases and two ramps providing access to the walkway along the top of the walls, one of which is internal and the other external. Each tower contained access stairs leading from the intervallum to the wall walk of town wall, of which a total of 21 have been discovered to date.
The defences of Lugo are the most complete and best preserved example of Roman military architecture in the Western Roman Empire.
Despite the renovation work carried out, the walls conserve their original layout and the construction features associated with their defensive purpose, with walls, battlements, towers, fortifications, both modern and original gates and stairways, and a moat.
Since they were built, the walls have defined the layout and growth of the city, which was declared a Historical-Artistic Ensemble in 1973, forming a part of it and becoming an emblematic structure that can be freely accessed to walk along. The local inhabitants and visitors alike have used them as an area for enjoyment and as a part of urban life for centuries.
The fortifications were added to UNESCO"s World Heritage List in late 2000 and are a popular tourist attraction.
