The old castle of Carros in the Alpes-Maritimes department was built in the Middle Ages, at the top of the village which strategically dominates the Var valley. Its presence, in the form of a first quadrangular keep with a cutaway to the south-east, is attested by written testimonies dating back to the beginning of the 12th century. It has retained a medieval stature with an alignment of crows on its eastern facade and buttresses. Acquired and renovated by the municipality, it has been transformed into an international center for contemporary art open to the public free of charge every day.
