MONUMENTA is an exhibition which takes place every 2 years where an artist creates a special piece of work to put inside the Nef of the Grand Palais: a glass-roofed steel building 137 metres high.

The balloon is made of special plastic, weighs 11 tons and was blown up (gonflé) inside the building. You could also go inside it, where you were surrounded (entouré) by red colour with strange dimensions.
