This in-situ installation (created for the site) offers immersion in the earth and water that shape our landscapes. Located above the gorges of the Bonnant, the exhibition questions this notion of the soil, its composition, its wear and tear with its deformations and what crosses it or inhabits it. This underground, invisible and changing world is constantly evolving and reshaping the landscape. This proposal seeks to reveal the territory of Saint-Gervais Mont-Blanc where Pile-Pont is located from below and what shapes it, the land, the water, the plants. Thus reversing the site, Benoit Billotte also proposes to contemplate differently our environment and to confront a temporality that exceeds us.
