A few steps from the entrance to the cave, the museum is an essential complement to the visit, accessible both before the start of the guided tour and after it.
The collections of archaeological objects taken from the cave during planned excavations and fortuitous discoveries are notably presented there. Among these objects are many achievements of the inhabitants of the Chalcolithic in stone, bone, wood or terracotta. It is a privileged place to discover the Paleolithic parietal art of the cave of Foissac, otherwise inaccessible. The museum also hosts temporary exhibitions, such as the one on the water cycle for summer 2016.
