The Château de Chazeron is a castle situated in the commune of Loubeyrat in the French département of Puy-de-Dôme, 3 km (1.9 mi) north-west of Châtel-Guyon. Originally a medieval castle, Chazeron was altered in the 17th century by the architect Jules Hardouin-Mansart. He built a staircase on the site of the keep and added an arcaded gallery. The moat was filled in, three of the external walls were demolished and two wings were added.
