About Centre des monuments nationaux
The Centre des monuments nationaux (CMN) is a French public institution under the Ministry of Culture that manages and promotes more than 100 historic sites and monuments across France, such as the Sainte-Chapelle, the abbey of Mont-Saint-Michel, the Panthéon, Carcassonne’s ramparts, and many others. It sells admission tickets, group visits, and special passes both on-site and online, including through its professional e-ticketing system often referred to as "e‑billetterie du CMN" or "billetterie pro".
A "CMN E‑Billets" or "CMN E‑BILLETS" line on a card statement is likely related to the online purchase of electronic tickets (e‑billets) or advance group tickets for one or more CMN-managed monuments. These may be individual dated e‑tickets, undated paperless passes, or bulk tickets purchased by organizations (such as schools, tour operators, or social committees) via the CMN professional ticketing portal. The amount can correspond to single entries, group reservations, or batches of tickets valid across a network of CMN sites for a defined period.
If you have questions about a CMN E‑Billets charge, start by checking any confirmation emails from the CMN e‑ticketing system and your spam folder, as well as your bank’s transaction date against the date you booked your visit. You can also log into the CMN’s online ticketing or professional e‑ticketing portal, where available, to review past orders and download invoices or tickets. For unresolved issues, use the contact details provided on the specific monument’s website or the CMN central contact pages, providing your name, purchase date, and any order or reference numbers shown in your email receipt or on the bank statement.
