Paris' iconic cauldron returns to light up summer nights

PARIS

A year after it captivated crowds during the Paris Olympics, a centerpiece of the summer Games made a comeback on June 22 to light up the French capital's skyline.

The iconic helium-powered balloon that attracted myriads of tourists during the Summer Games has shed its Olympic branding and is now just called the “Paris Cauldron.” It rose again into the air later on June 22, lifting off over the Tuileries Garden just as the sun was about to set.

After Saturday's flight, the balloon will lift off into the sky each summer evening from June 21 to Sept. 14, for the next three years.

The cauldron’s ascent may become a new rhythm of the Parisian summer, with special flights planned for Bastille Day on July 14 and the anniversary of the 2024 opening ceremony on July 26.

The 30-meter-tall floating ring, dreamed up by French designer Mathieu Lehanneur and powered by French energy company EDF, simulates flame without fire: LED lights, mist jets and high-pressure fans create a luminous halo that hovers above the city at dusk, visible from rooftops across the capital.

Though it stole the show in 2024, the cauldron was only meant to be temporary, not engineered for multi-year outdoor exposure.

To transform it into a summer staple, engineers reinforced it. The aluminum ring and tether points were rebuilt with tougher components to handle rain, sun and temperature changes over several seasons. Though it’s a hot-air-balloon-style, the lift comes solely from helium — no flame, no burner, just gas and engineering.
