The Ephemeral City

Olivier Grossetête

Gigantic cardboard buildings

In Mexico City, Sydney, Helsinki... and now in Paris, plastic artist Olivier Grossetête imagines in the course of his travels gigantic cardboard sculptures, some of which can reach 80 feet in height and weigh over a ton. These site-specific structures are an opportunity for the public to take part in an unprecedented human and artistic experience: coming together to build, without a crane or any type of machine, a utopian and ephemeral construction. Residents, tourists, passers-by, young and old – everyone is invited to participate in the performance which relies exclusively on the energy and hands of the participants. From the construction of the first boxes to the final demolition, it is collective strength which enables the materialization of what was at first a "childhood dream".
