Pepin of Landen
The abbey was founded by Itta of Metz, the widow of Pepin of Landen, Mayor of the Palace of the Kingdom of Austrasia, with their daughter, Gertrude of Nivelles. Christianity was not at all widespread in that place and time. It was only the development of cities and the initiative of bishops that led to a vast movement of evangelism, which led to the flowering of monasteries everywhere in the seventh and eighth centuries.
