Created in situ, each work in this permanent collection guides visitors towards an extraordinary place or noteworthy site: a house in the Loire (Maison dans la Loire by Jean-Luc Courcoult), a limp boat (Erwin Wurm), a starry garden (Jardin étoilé by Kinya Maruyama), a sea snake (Serpent d’océan by Huang Yong Ping), or a series of triangles (Suite de triangles by Felice Varini).

Every site can be accessed freely. From April to October, a cruise boat leaving from Nantes sails to Saint-Nazaire and allows visitors to also discover the river and its banks.
