Place de Stravinski	Paris
	Ile de la Cite

Proceeded by a Gallo-Roman temple to Jupiter, a Christian basilica, and a Romanesque church, construction of Notre-Dame de Paris began in 1163 during the reign of Louis VII. Pope Alexander III laid the foundation stone. The idea to replace the Romanesque church occupying the site - the Cathedral of St. Etienne (founded by Childebert in 528) - was that of Bishop Maurice de Sully (who died in 1196). Construction was completed roughly 200 years later in about 1345. The choir was completed in 1182; the nave in 1208, and the west front and towers circa 1225-1250. A series of chapels were added to the nave during the period 1235-50, and during 1296-1330 to the apse (Pierre de Chelles and Jean Ravy). The transept crossings were build in 1250-67 by Jean de Chelles and Pierre de Montreuil (also the architect of the Sainte-Chapelle). It was essentially completed according to the original plans. .
