To celebrate its 10 years, le Centre Pompidou-Metz is inviting Giuseppe Penone to take over its Forum for a protracted duration. The artist will implant in this freely accesible space, largely open to the exterior and remarkably high, an unprecedented installation: the bronze cast of a walnut tree of around 15 metres high and of which certain segments and ramifications will be in white marble.

The branches of the tree and the splayed framework of the Centre Pompidou-Metz, designed by Shigeru Ban, will enter into resonance, sharing the similar structure of a meshed parasol. Plant growth, melting of an alloy and solidification of stone: the elements brought together in Indistinct confini – Noce (« Indistinct Frontiers - – Walnut ») form a hybrid wood both mineral and metallic, immaculate, and weathered the artist however sees in these different materials the continuum of a unique material, engaged at different moments with fluidity and dispersal.
