 In 1039, the remains of Monulph (and Gondulph) were elevated in a ceremony attended by Henry III, Holy Roman Emperor.Humbert, the then provost of the chapter of Saint Servatius, placed a cenotaph in the axis of the newly built 11th-century church.This cenotaph, which was removed in 1628 and rediscovered in 1890, can now be seen in the eastern crypt of the church.
