Tobias Rehberger installed a very special potato field (in 2009) which, according to the legend he built around it, contains a golden potato. The potato field actually cultivated measures 185 m2. Initially, the potatoes were collected and the first harvests were given to the Restos du Coeur. This work is part of a larger ensemble that the artist has created for the entire line 1 of the tram. Other works by the same artist can be seen in front of the fire station, on the facades of the PAX, at the tram stop Musée de l’auto, etc.
