Fodor's Expert Review Musée Requien
Don't bother to rush to this eccentric little natural history museum, but since it's next door to the Calvet Museum (and free) you might want to stop in and check out the petrified palm trunks, the dinosaur skeleton, the handful of local beetles and mammals, and the careful and evocative texts (French only) that accompany them. The museum is named for a local naturalist and functions as an entrance to the massive library of natural history upstairs.
