The Crypte archéologique de l'île de la Cité is an underground archaeological museum set beneath the forecourt of Notre-Dame Cathedral. Opened in 1980, it preserves remains uncovered during excavations in the 1960s and 1970s, including Gallo-Roman baths and ramparts, medieval cellars, and the foundations of vanished churches and hospitals. Run by Paris Musées, it traces the urban evolution of the Île de la Cité across two millennia, with 3D reconstructions bringing successive eras of the city to life.
