The canons used to celebrate their services in a three-nave basilica with a transept, three east apses and westwork with two octagonal towers with a bell chamber between them, and a simple narthex. Under the choir was a crypt, and over the intersection was another tower. The church was consecrated on 2 July 1051, by Archbishop Hermann of Cologne and dedicated to Simon the Zealot and Jude the Apostle, whose saint's day coincided with Henry III's birthday.
