Alto of Altomünster was an 8th-century Benedictine abbot who lived and worked in the Duchy of Bavaria. Originally an Irish monk, he is traditionally identified as the founder of Altomünster Abbey, which eventually led to the development of a surrounding market town. Before establishing his monastery on land donated by King Pepin the Short, he reportedly lived as a hermit in the regions near Munich and Augsburg. He is recognized as a saint within the Catholic Church.
