Discover the extraordinary journey from Venice to Paris of a monumental work by Giambattista Tiepolo. This 18th century work, a 30 m2 fresco, now adorns the magnificent staircase of the Jacquemart-André Museum in Paris. The local authorities were strongly opposed to the departure of a work made by a painter then considered the greatest decorative painter of his time. The Jacquemart-André were within their rights, and they have the authorization to buy and export the frescoes. But how to detach a fresco from a wall? The operation is delicate, restorers have specialized in this exercise, and it is the famous Giuseppe Stefannoni, who will undertake the task.
