A modest, lived-in castle in the centre of town, originally 13th century but rebuilt in the 17th. Since 1976 it has been the headquarters of the Parc National des Cévennes, and the ground floor doubles as the park's visitor information centre — maps, exhibits on the local geology and wildlife, advice on walks and rangers' routes. The interior courtyard and walled garden are pretty in their own right.
Free to enter the courtyard and the information centre. The keep can usually be climbed for a small fee.
