Saint Kilian
Saint Boniface came to Franconia in 719 and at that point there was no duke at Würzburg any more. Even some of the local clergy practiced pagan customs. Boniface appointed his follower Saint Burchard as the first Bishop of Würzburg in 741. Saint Mary's Church (explicitly mentioned in a document from 822) became the See's cathedral. Over the next decades, the town of Würzburg began to grow and in 788 the hill-top church lost the role of cathedral to a predecessor of Würzburg Cathedral (except for a brief interlude after the latter was destroyed in a fire in 855). At that point, the remains of Saint Kilian, Saint Colman and Saint Totnan were moved from Saint Mary's to be reinterred at the new cathedral. However, Saint Mary's continued to serve as the burial site for the intestines of the Prince-Bishops. Their bodies were buried in the cathedral, their hearts until 1573 at Ebrach Abbey.
