The Champs-Elysees, has been covered in earth and turned into a huge green space in an event staged by young French farmers.
Plants, trees and flowers were brought in by lorry overnight to transform the avenue into a long green strip.
More than a million people are expected to visit over the next two days.
The event has been organised by the French Young Farmers to showcase farm production from sheep breeding to crop growing.
The union, which represents some 55,000 farmers under the age of 35, wants to impress on the public – and the government – the efforts required to produce what goes on the table.
“It’s about re-establishing contact with the public about what our profession is and what they want from it,” William Villeneuve, president of the Jeunes Agriculteurs, said on Friday.
