Rosny-sur-Seine, in the Yvelines department, invites you on Friday, May 29, 2026, for the 7th edition of "Mille et un Feux." Set in the Château Park, the evening begins with a lantern procession before giving way to a drone-sculpted sky by 250 drones, followed by a spectacular fireworks display. A free, open-access event where the château’s heritage serves as the backdrop for an open-air show.
