You can find this art object on Westersingel. The Italian artist Giuseppe Penone was inspired by a fallen tree whose roots grew on the ground. Around the art object are five living trees that live in symbiosis with the object. The bronze roots stick with their ends in the five surrounding living trees. Because the living trees continue to grow, the bronze will leave a trace in their bark. Penone uses the passage of time in the work of art: after years the elapsed time will be visible in the tree trunks.
