This spring, discovered in the 19th century, is situated not far from Pouhon Pierre le Grand issues from the same water table. It is differentiated by a richer mineral content, acquired during the final part of its subterranean journey. In equilibrium with the 19th century glass wall surrounding the original building which housed the spring, the current pyramid is designed to reflect architecture from the end of the 20th century. Art exhibitions are held here throughout the year.
Open only for exhibitions from Thursday to Sunday, 2 pm to 6.30 pm.
