The sessions are aimed at specific age groups: sessions for children (3-4 years old/4-8 years old/6-10 years old) and sessions for teenagers/adults (accessible from 8 or 12 years old, depending on the topic).

Access to the sessions is strictly prohibited for children under 3 years old.

Nantes is transforming

Nantes has been getting a major makeover since 2024.

The city is currently undergoing extensive public works, particularly around Île de Nantes (Quai de la Fosse and the Pont Anne-de-Bretagne bridge). Tram Line 1 will be temporarily suspended from mid-June to late August 2026. The city centre and Parc des Chantiers – Machines de l’Île will remain accessible, thanks to replacement buses and to the pedestrian and cycling routes that will continue to be open. Park-and-ride facilities are available to drivers.
