2024 Summer Olympics cauldron, Olympic cauldron in Tuileries Garden, France

The Paris 2024 cauldron is a 7-metre-diameter metal ring suspended beneath a 30-metre helium balloon, moored over the Grand Bassin Rond in the Tuileries Garden. Its flame is simulated by 40 LED projectors lighting mist from some 200 high-pressure water nozzles, so no fuel burns. Designed by Mathieu Lehanneur, it is ringed by a low wall engraved "PARIS 2024".

Mathieu Lehanneur designed the cauldron, unveiled at the opening ceremony on 26 July 2024, when Teddy Riner and Marie-José Pérec lit the 7-metre ring. It operated at the Tuileries until 14 September 2024, then was reinstalled each summer from 21 June 2025 to 14 September, up to the 2028 Games, without referring to the Olympics.

The cauldron was lit on 26 July 2024 by judoka Teddy Riner and sprinter Marie-José Pérec, both born in Guadeloupe, during the opening ceremony. Since 2025 it returns each summer from the Fête de la Musique on 21 June to 14 September, and Parisians have petitioned to make it a permanent fixture.

The basin stands near the round pond in the garden and is visible from the paths during the day even without lighting. Evening displays take place on selected days, and a walk along the avenues leads directly to the site.

The balloon uses helium instead of hot air, so it floats gently above the water in calm weather. The 200 nozzles on the ring produce mist that looks like flames in the lamplight without releasing heat or smoke.
