In 983 Emperor Otto III confirmed his rights within the Duchy of Lower Lorraine to properties and territories in the counties of Maasland, Kinhem (Kennemerland) and Texla (Texel), thus stretching along the entire Hollandic coast (as well as inland).
Dirk II rebuilt Egmond Abbey and its wooden church in stone to house the relics of Saint Adalbert, the project starting in 950.
