Some History:
Notre-Dame's first version was a "magnificent church" built by Childebert I, the king of the Franks at the time, in 528, and was already the cathedral of the city of Paris in the 10th century. However, in 1160, having become the "parish church of the kings of Europe," Bishop Maurice de Sully deemed the building unworthy of its lofty role, and had it demolished.
Construction on the current cathedral began in 1163, during the reign of Louis VII, and opinion differs as to whether Bishop Maurice de Sully or Pope Alexander III laid the foundation stone of the cathedral. The cathedral was completed around 1345
