Millions of pilgrims visit St. Gabriel's shrine in Isola del Gran Sasso d'Italia near Teramo each year to see Possenti's burial place and the monastic house in which he lived out his final years. There is an ongoing tradition every March, when thousands of high school students from the Abruzzo and the Marche regions of Italy visit his tomb 100 days before their expected graduation day and pray to him in order to achieve good scores on their final. Every two years, from mid-July to the beginning of October, the Italian Staurós ONLUS foundation hosts at the Sanctuary of Saint Gabriel a celebrated exposition of contemporary religious arts. With an average of 2 million visitors per year, this is one of the 15 most visited sanctuaries in the world.
