Crypte archéologique de l'Île de la Cité
Laid out beneath the Notre-Dame forecourt and opened in 1980, the archaeological crypt preserves in situ the remains uncovered while digging a car park in the 1960s: Gallo-Roman quays, a hypocaust, sections of the late Roman rampart, medieval cellars and foundations of the Hôtel-Dieu.
It is the best place to grasp the layering of Paris, from Lutetia to the 19th century, in a single reading. The space is cool, quiet and rarely crowded, metres away from the crowds above. Tip: visit the crypt before the cathedral — Notre-Dame reads differently afterwards.
