Notre-Dame & The Archaeological Crypt

The parvis of Notre-Dame hides a secret: an entire world of ancient Paris preserved beneath the pavement. This semi-private tour invites an intimate group of five to explore the contrast between the cathedral's vertical Gothic ambition and the archaeological remains of the Roman city. Guided by a state-licensed expert, you move from the soaring nave to the subterranean halls where medieval foundations and Gallo-Roman ruins tell the story of two thousand years of urban life. It is an experience that places the cathedral in its true context — as a monument built upon the very foundations of Parisian civilisation. In this focused small-group setting, history is not merely told, but discovered.
