This route begins in the woods, at a spot known as Le Grand Tienne. It passes close to the ruins of the Mediaeval castle of Fagnolle, which was built from Calestienne limestone. Built on a cadastral lot at the end of the 12th century, this Mediaeval fort is one of the few examples of a ‘château-fort de plaine’ or ‘plain fort’ in the region. At the high point of the village, the route continues towards Matagne-la-Grande and Matagne-la-Petite, where the unfolding fields and woodlands offer exceptional views. Next, discover the Chapelle Saint-Hilaire, which was built during the 11th century. You will return towards Fagnolle exclusively via the old rail line.
