Centre de loisirs dit Le Balcon de Belledonne, La Baleine

The Centre de loisirs dit Le Balcon de Belledonne, designed by architect Pascal Haüsermann, was constructed between 1963 and 1966 at an altitude of 1,200 meters in Sainte-Marie-du-Mont, France. Originally functioning as a restaurant, it offered patrons tranquility, stunning views of the Belledonne mountain range, and amenities such as a solarium, swimming pool, and sauna. The building's unique whale-like shape has led locals to nickname it accordingly. Currently, the center is abandoned, with its concrete exterior now covered in moss, and it is situated on private property.
