Gather outside the building door at the meeting point on Île de la Cité — your guide will be waiting to welcome the group.

Walk the island's streets as your guide traces how this small landmass grew into the political and spiritual centre of France.

Pause to learn about the dual role this royal chapel played — both as a spiritual sanctuary and a statement of royal power.

Stroll past the flower market, one of the oldest in Paris, as the guide weaves in the social history of the neighbourhood.

Arrive at the cathedral's parvis and take in the full sweep of the Gothic facade, towers, and flying buttresses with your guide's commentary.

Use the included audio guide to discover the cathedral's architectural and historical details at your own pace.

Descend into the crypt beneath the parvis to explore Roman-era ruins and medieval remains excavated below street level.
