Giovannangelo Porro was a 15th-century Italian priest and hermit belonging to the Servite Order. Born into a noble family in Barlassina, he entered the religious life following his father's death. He spent much of his life practicing intense meditation and penitential acts, including fasting and self-mortification, while living in various convents located in Florence and Milan. He died in Milan in 1505, leaving behind a legacy of deep spiritual devotion and local veneration.
Life and devotion

After joining the Servites in 1470, Porro moved to Florence, where he was ordained. He spent approximately twenty years at the Monte Senario convent focusing on inward meditation. Later in life, he resided in Chianti and Lodi before returning to the Milanese region. He was known for his affinity for nature and his rigorous ascetic lifestyle, which he maintained until his death in October 1505.
Veneration and miracles
Following his death, his tomb attracted pilgrims seeking healing. A notable instance involved the childhood healing of Charles Borromeo, who reportedly recovered from illness through Porro's intercession. Borromeo later kept a bone fragment from the incorrupt remains of the priest. Porro was beatified by Pope Clement XIII in 1767, recognizing the long-standing popular devotion directed toward him.
