Setting the scene
Bishop Maurice de Sully launched a new cathedral for Paris around 1163 on the Île de la Cité, replacing older churches with early Gothic experiments in pointed arches and flying buttresses that let masons pierce walls with stained glass narrating scripture for largely illiterate congregations.
What happened
Notre-Dame's main construction was completed around 1345, its twin towers, rose windows, and choir statuary making it the ceremonial heart of French royal and religious life for centuries.
Why it still matters
The 2019 fire shocked the world when flames consumed the oak roof and spire; global donations funded a painstaking restoration that reopened the nave to worshippers and tourists, renewing arguments about medieval craft and modern fire prevention.
