Named after the 4th-century missionary, Florus, this medieval town is built from volcanic rock atop column-like naturally formed basalt cliffs. Thanks to its excellent defensive position, Saint Flour withstood the English onslaught during the Hundred Years’ War. Follow the way marked walking circuit to key sites. Depart from the tourist office in the central square, La Place d’Armes, and follow the medieval city walls all the way down to the Sainte-Christine district beside the Ander. From here, you’ll see striking viewpoints onto the Upper Town. Follow in the footsteps of the pilgrims via the steep climb back up the Main de Saint-Flour (Saint Flour’s Hand). This is where the pilgrims came to see the imprint of Saint Florus’ hand in the rock, where he miraculously opened a breach in the solid lava, allowing him to create his oratory on the summit. The story of Florus is written in the stained-glass windows of the medieval Saint-Pierre Cathedral, host to a 12th-century wooden Christ.
