At an altitude of 1600 m, at the heart of the Catalan Pyrenees, and at the crossroads of Conflent, Capcir and Cerdanya, the town of Mont-Louis, founded in the 17th century in response to the order of King Louis to secure the area after the Treaty of the Pyrenees was signed in 1659, is the highest walled town in France! Built by Vauban, from 1679 to 1681, this ancient stronghold can also pride itself in being included in the UNESCO World Heritage Site list, because of Vauban's fortifications. Take a stroll and see the Porte de France, the ramparts, the Church of St Louis and the solar furnace dating from 1949. You can learn about how the furnace works on a guided tour.
