Notre-Dame de Paris stands on the Île de la Cité, and since the end of 2024 it is open again, its limestone scrubbed pale after a five-year restoration. You approach across a stone parvis, and the west front rises in careful symmetry: two square towers, a gallery of kings, and deep-carved portals that served medieval Paris as a Bible in stone. Step inside and the nave draws your eye upward into cool shadow. Three rose windows fill the interior with coloured light.
Building began in 1163 and took nearly two centuries. This was among the first great churches to raise the flying buttress, external arches that carry the roof's weight outward and free the walls for wide sheets of glass. The fire of April 2019 destroyed the roof and toppled the spire, but the great stone vaults largely held, and hundreds of craftspeople rebuilt the oak beams as before. France still measures road distances from a bronze star set in the square outside.
