Notre-Dame Cathedral

It was begun in 1163 under Bishop Maurice de Sully and finished around 1345. On 15 April 2019 a fire destroyed the wooden roof, known as «the forest», and Viollet-le-Duc's spire. After five years of work it reopened in December 2024, with the spire rebuilt as before and the stone cleaned.

The towers have been open to climb again since September 2025: 424 steps up to the gallery of chimeras, the gargoyles that look out over Paris. In front, in the paving of the square, is «point zero», from which France's road distances are measured.
