Monulph

Louis Duchesne has suggested that Monulph succeeded Saint Servatius directly (in contradiction with the account of the sixth-century bishop and historian Gregory of Tours).

[3] According to Gregory of Tours in his Liber de Gloria Confessorum, Monulph built a large stone church (templum magnum) on the grave of Saint Servatius, just outside the castrum of Maastricht.

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.

Another tradition holds that Monulph founded the chapel of Cosmas and Damian in 588 at the river confluence of Meuse and Ourthe, in a place that would later become the city of Liège.
