On October 24, 1260, the spectacular Cathedral of Chartres was dedicated in the presence of King Louis IX of France. From the article:
"Partly built starting in 1145, and then reconstructed over a 26-year period after the fire of 1194, Chartres Cathedral marks the high point of French Gothic art. The vast nave, in pure ogival style, the porches adorned with fine sculptures from the middle of the 12th century, and the magnificent 12th and 13th century stained-glass windows, all in remarkable condition, combine to make it a masterpiece.
The construction project used the plans laid out by the first architect in order to preserve the harmonious aspect of the cathedral. Work began first on the nave and by 1220 the main structure was complete, with the old crypt, the west towers and the west facade incorporated into the new building. On October 24, 1260, the cathedral was finally dedicated in the presence of King Louis IX and his family. Chartres Cathedral was never destroyed nor looted during the French Revolution and the numerous restorations never have altered its glorious beauty. It always stayed the same: a great triumph of Gothic art.
Not only is Chartres Cathedral one of the greatest achievements in the history of architecture, it is almost perfectly preserved in its original design and details. In addition to its architectural splendor, Chartres Cathedral has been a major pilgrimage destination since the early Middle Ages. Its venerable history, exquisitely preserved architecture, and centuries of fervent devotion make for an atmosphere of awe and holiness that impresses even the most nonreligious of visitors.
The cathedral was added to UNESCO's list of World Heritage Sites in 1979."
