The Château de Beaulon is a château—castle located in the town of Saint Dizant du Gua, near the southwestern coast in the Charente-Maritime Department of the Poitou-Charentes region, in France.
The privately owned château, gardens, and landscape park, a Monument historique, are open to the public.
A major feature of the landscape park are the Fontaines Bleues, natural springs whose waters are an unusual brilliant hue of blue.
There is also a round dovecote structure with a conical roof, dating from 1740, with fifteen hundred nesting holes.
The gardens suffered major damage from the storm of 1999, which blew down hundreds of trees.
