 Margrete seems to have shown a particular interest in Stavanger.She was engaged in a conflict with the bishop of Stavanger, a conflict which was solved by Cardinal William of Sabina, who granted her patronage rights over three chapels in Stavanger, one of them possibly Peterskirken (1247).Margrete was also, at an unknown date before 1245, the first witness to Haakon's official confirmation of the authority of the church and the crown over Stavanger.
