The Château de Belpuig is a ruined castle in the commune of Prunet-et-Belpuig in the Pyrénées-Orientales département of France.
Situated a 15 minutes walk from the village, the castle occupies a strategic position on a rocky spur overlooking the surrounding countryside. The extensive panorama takes in the mountain ranges of Canigou, the Albères, the Corbières and the coast of Languedoc and Roussillon[1].
