According to Bunson, Eichstätt was the site of Willibald's most successful missionary efforts, although specific details like the means of conversion and number of converts are not known. The monastery was one of the first buildings in the region and served as an important centre, "not only for the diocesan apostolate, but also for the diffusion and development of monasticism." Wilibald served as the bishop of the region in Franconia for over four decades, living in the monastery and entertaining visitors throughout Europe who would come to hear of his journey and monasticism.
