Below the Hohes Schloss is the Baroque complex of the former Benedictine monastery of St. Mang, whose history goes back to the 9th century. Füssen has Saint Mang (Magnus of Füssen) as its patron saint. He and his Benedictine brother Theodor were two monks from the Abbey of Saint Gall and are considered to be its founders, in addition to the Monastery of Kempten.[2] Magnus' original burial place was in the small chapel he built.
