San Marco is a little village situated on the Departmental Road to Sauze d’Oulx, at 1212 m. above sea level. It was on the way called “Antica Strada di Francia” coming from Oulx and going to Amazas and Cesana. In 1562 it was the scenery of a cruel fight between Catholics and Waldesians during the Religion War. Here was born the Waldesian Pastor Claude Perron. The chapel dedicated to Saint Mark Evangelist is already mentioned in the Bishop Cunibert Bill of 1065; it preserves a baroque Ancona and on the exterior walls some sixteen-century frescoes traces are still visible. Nearby the chapel there are a sixteen-century fountain and the Lime tree of Liberty dating back to the years of the French Revolution. On the walls of the village you can admire six nineteen-century sundials
