Magnificent view of the historic center, with the river it makes a magnificent landscape. A bit of a shame that there is the main road not far away with the incessant noise of cars... but it's still worth it!

Nestled in Ariège, Saint-Lizier offers a dive into the past with its preserved medieval heritage. Ranked among the most beautiful villages in France, it seduces with its cathedral and its frescoes. Formerly an episcopal seat and a stopover on the way to Santiago de Compostela, this quiet village has perfectly preserved its older buildings and is worth a detour.
