Ancient and Medieval Periods
Iron Age (6th century BC): The site of Clermont-l'Hérault was inhabited during the Iron Age, serving as one of the main Oppida (fortified settlements) of the Celtic Mediterranean
Roman Era: Archaeological excavations have revealed a significant Roman settlement, including a thermal establishment, indicating its importance during antiquity
Medieval Period: The town was built on the slope of Pioch Castel, crowned by the Château des Guilhem, a medieval castle.
Château des Guilhem Origins and Construction (11th–12th Centuries)
Built by the Guilhem family, lords of Clermont-l'Hérault, between the late 11th and early 12th centuries on Puech Castel hill, a strategic site overlooking the Hérault Valley and key routes to Bédarieux.
Evidence suggests earlier structures may have existed, dating back to the Iron Age or Roman period.
The castle was part of a fortified feudal town, with ramparts added later to protect the settlement.
Despite its imposing medieval presence, the castle has a history of dramatic incompetence when it comes to staying "closed" to the public. After being shut in 2009 due to falling stone risks, it defiantly reopened in 2013—only to be closed again in 2018 by a municipal decree for the same reason. Locals joke that the castle’s most consistent feature is its "now you see me, now you don’t" policy for visitors
