ONE OF THE OLDEST MONASTIC FOUNDATIONS IN BELGIUM
Sigebert III, the Merovingian king of Austrasia and eldest son of the famous king Dagobert I, had a charter drawn up authorising the foundation of an abbey in the royal forest of Ardennes. On the advice of his mayor of the Grimoald Palace, Sigebert III decided that this abbey would be composed of two monastic communities, placed under the direction of one single abbot.
