Located at the northern end of the Erdre promenade, on the course of the 50-Otages in Nantes, this building is set in an urban landscape marked by the confluence of the Erdre, Sèvre, and Loire rivers. The building is situated at the corner of Place du Port-Communeau, in the heart of a territory shaped by a crystalline base and river valleys with peaty and sandy soils, reflecting the geological and human history of the city.
