Château de Chabrillan, Medieval castle in Chabrillan, France.

Château de Chabrillan is a ruined castle of pale beige and grey stone on a rocky base in the commune of Chabrillan. On the north side stands a square keep about 20 m high with walls almost 2 m thick; to the south a round tower, added later, and between them further buildings once formed a complete fortress. A well on the east side supplied water.

The castle was first documented in 1150 and belonged to the Chabreihha family, who inhabited it over several centuries. The Moreton family departed the premises in 1650, ending its continuous use as a residential fortress.

The castle's name comes from the Chabreihha family, recorded as its owners in 1150. A 1634 document mentions a room set aside for playing tens, a board game, showing that the fortress also served as a residence. The Moreton family left around 1650, but their descendants still own the ruin.

The castle is privately owned and stands in ruins, so it is not a staffed visitor site; view it from the village and its surroundings. The keep entrance was originally about halfway up, reached by a wooden ladder, so the structure is not meant for climbing.

During the French Revolution, the castle lost its roof and served as a stone quarry, with its materials repurposed throughout the commune. This transformation shows how political upheaval and practical needs reshaped the fate of even long-standing structures.
