Every year, the Heritage Days invite curious visitors of all ages to discover Parisian and Île-de-France heritage in a new light. For one weekend, that is the September 19 and 20 for this edition, monuments, churches and other institutions that are sometimes rarely open to the public reveal their behind-the-scenes through tours and activities often free of charge.
For this 2026 edition, a completely unprecedented opening enriches the programme: access to the FDJ UNITED studios, located in Boulogne-Billancourt. To mark the 50th anniversary of the Loto, the institution invites the general public to step through the doors of a venue that is normally closed to visitors, to dive into the heart of a television and popular ritual that has punctuated the daily life of millions of French people for half a century.
Throughout the weekend, this exceptional tour offers a behind-the-scenes look at the making, the history of the show’s legendary draws, and the secrets of production and the technology that bring the broadcasts to life. Visitors will be able to explore the filming sets, learn how the game has evolved since its 1976 debut, and understand the high-security workings behind a televised draw.
Heads up, spots over these two days will be limited, with registration opening on September 1 at 12:00 PM on the FDJ United site.
Take a look behind the scenes as we celebrate 50 years of LOTO!
