Origin and history

Fort Liberia was built from 1681 by Vauban, after the Treaty of the Pyrenees which rallied the Roussillon to France. Located on the heights of Villefranche-de-Conflent, it aimed to strengthen the defence of the Tet Valley, considered vulnerable. Vauban conceived it as a deterrent complement to the Mont-Louis citadel, at 1,600 m above sea level, to control strategic access between the Tet, Rotja and Cady valleys.

In the 17th century, the fort served as a state prison under Louis XIV, welcoming inmates in the poison case, such as Anne Guesdon and La Chapelain, sentenced to life imprisonment (36 and 43 years). Symbol of absolutism, it isolated prisoners, deprived of any outside contact. His only warrior episode took place in 1793, during the Revolution: bombarded by the Spanish, he capitulated, revealing his defensive limits (inefficient canons, reduced visibility).

In the 19th century, Napoleon III dug an underground staircase of 734 steps (1850–53) to connect the fort to the city, 150 meters below. Disused by the army, it was sold in 1925 to Mr Laurens, who planned to install a nursing home for sailors. The difficult access and distance from the sea made the project impossible. In 1955, Marcel Puy acquired it before restoring it and opening it to the public in 1987, via an emphyteotic lease with local traders.

Ranked a historic monument in 2009 and a UNESCO World Heritage Site in 2008 (Vauban Fortifications Network), Fort Liberia is now a private property. He also served as a set for the film Le Bossu (1959) with Jean Marais. Its architecture illustrates Vauban's military engineering, adapted to the topographical constraints of the Pyrenees.

The underground staircase, a 19th century technical masterpiece, and the remains of the ramparts restored after 1793 testify to its evolution. The casemates and courtyards, partially remodelled in the 20th century (such as the destruction of the officers' barracks by Mr. Laurens), reflect its successive uses: prison, aborted retirement project, and then tourist site.
