Why come
Isola del Gran Sasso d'Italia sits in the Mavone river valley, with the southern wall of the Gran Sasso massif rising directly behind it. The commune's territory climbs from the valley floor to Monte Corno, the highest peak in the Apennines outside Sicily. The Sanctuary of San Gabriele dell'Addolorata stands at the foot of the massif on the site of a convent traditionally said to have been founded by Francis of Assisi around 1215.
Passionists arrived in 1847, and the young Gabriele Possenti reached the retreat in 1859 and died there in 1862 at 24. He was canonized in 1920. The complex now draws roughly two million pilgrims a year, with a 1970 concrete-and-glass church seating six thousand.
Above the sanctuary, the Corno Grande and Corno Piccolo peaks are reached by trails from the Mavone valley. The town itself is small. The pilgrims come for the saint, the climbers for the rock.
