In a document dated March 1187 and addressed to William II, Archbishop Gualtiero begged the king to move the remains of the royal family, which were in the chapel of St Mary Magdalene, to another chapel, yet to be built in a nearby area. The reason was that the chapel was an impediment to ecclesiastical celebrations. A misinterpretation of the document suggested that Gualtiero had ordered the demolition of the Magdalene chapel.
