On the first level of Fort Libéria – a defense fort that sits above Villefranche-de-Conflent – stood the officers’ barracks. All that remains today is the lower part, the chapel, and the crypt as well as the food reserves under the slab of the main courtyard. The most recent part of the castle is the steeple, a copy of Romanesque architecture added in 1930. The imposing Catalan wrought iron balusters that line the rampart walk are made from iron extracted from the Canigou and worked according to the process of the Catalan forge. This process has the reputation of making the ore particularly malleable and very little subject to rust. This iron has therefore remained in remarkable condition after three centuries of existence.
