When Norbert of Xanten, founder of the Premonstratensian Order, was returning from Cologne in the year after its foundation with relics for his new church at Prémontré, Godfrey, Count of Namur, and his wife Ermensendis received him in their castle at Namur. He made such an impression on them that they asked him to found a house at Floreffe nearby. The charter by which they made over a church and house to Norbert and his order is dated 27 November 1121, so that Floreffe is, chronologically speaking, the second abbey of the order. Norbert laid the foundations of the church, which was called Salve ("Save"); the abbey was named Flos Mariae (the "Flower of Mary").
