“Stones possess something indescribably serious, invariable and extreme, something imperishable or already perished. They captivate through an intrinsic, infallible, immediate beauty, that is accountable to no one.” Roger Caillois (1913–1978) A guide for your visit, and a souvenir. A journey through time and the many spaces at the Gallery of Mineralogy and Geology, from its permanent exhibition Treasures of the Earth and the Muséum’s reserves, to the Rock Garden.
