How it works
Choose a visit window, get your digital guide immediately, and ask us to attempt the optional official reservation process.

Cathedral admission and the optional official reservation are free.
We attempt the official reservation process using your selected visit window; the cathedral controls availability.
Digital companion content is delivered immediately after payment. If assistance succeeds, the official reservation document is forwarded without editing names or page content, usually the same day or one day before.
Notre-Dame Companion is an independent reservation-assistance and digital-guide service operated by FON Group, Inc. It is not affiliated with or authorised by Notre-Dame de Paris, the Diocese of Paris, or any public institution. Cathedral admission and optional official reservations are free. Your payment covers our assistance, self-guided digital companion, and support—not admission, priority entry, or special access. Official availability and admission remain controlled by the cathedral.
