Exclusive: Scale model found in Christo’s studio leads to London realisation of internally lit Air Package on a Ceiling

Christo once wrapped up the Reichstag, suspended a curtain across a Colorado valley and covered up the Pont Neuf in Paris. Now, six years after the artist’s death, a London gallery is to create a monumental installation he designed in 1968, using a detailed scale model and drawings that had been presumed lost until their chance discovery.

Christo had imagined a vast, internally illuminated suspended form, like a cloud, but technical constraints meant the plan was never brought to fruition.
