Veit Stratmann, a visual artist, was the first to examine the subject. At the end of 2011, he submitted his report entitled “The Hill”. To combat memory loss, he proposes a ritual every 30 years. The final cover of the storage centers would be raised regularly. At the end of 300 years of monitoring, the final cover would reach a height of 57 meters and become a hill.
He has taken part in exhibitions at the Centre d’art et de Diffusin Clark, in Montreal, at La Force de l’art at the Grand Palais in Paris in 2006, at the MAC/VAL, Musée d’Art Contemporain du Val-de-Marne and an exhibition entitled The element for the city at the Nevada state Museum of Arts.
