The museum presents the geology, paleontology and archaeology of Mormoiron. The history of ochre, gypsum, siliceous sands, clay and gravel pits of Mormoiron is evoked. Many photographs and videos explain the geological phenomena of these transformations. From the Palaeolithic to the Gallo-Roman period, a collection of fossils, flint and pottery are offered to the visitor. This one cannot miss the casting of a skeleton of Palaeotherium (38 million years), fossil mammal extracted from the quarries of Mormoiron in 1904. It is one of the few found to be complete to date. The museum is part of a rich architectural and natural heritage. You can continue your visit, thanks to an orientation route, "the sands of Mormoiron".
