The small town of Ronse is a rarity in the Plat Pays (flat country) of Flanders, situated as it is in the hills of the Ardennes. The church of Saint Hermes, which was later built on top of the crypt, was in 1129. A pilgrimage in honour of the saint, who had by then be known to cure mental illnesses, sustained the local economy.
