Fort Libéria is a former military installation in the French commune of Villefranche-de-Conflent in the department of the Pyrénées-Orientales.
Constructed to defend the newly acquired territory of the Roussillon following the Treaty of the Pyrenees (1659), it was designed by Louis XIV’s military engineer Sébastien Le Prestre de Vauban on a hill above the village of Villefranche-de-Conflent.
The fort was occupied by a garrison of 100 people and their officers, and equipped with ten cannons. It was only attacked once, and lost its military function in the 19th century.
The fort is open to the public. Access is either on foot, via a sometimes steep road; by minibus; or by the subterranean staircase
Military caserne
It also functioned as a prison. On multiple occasions the fort served as a prison for women, with a "prison pour dame" equipped for the purpose.
