Pier Giorgio's parish church in Turin, from where he was confirmed and buried, is known by the locals as "La Crocetta" because of its location near an intersection. (The official name is "Our Lady of Grace." The street address if you're planning to visit is Corso Einaudi 23 - 10129 Torino. Visit the church website for Mass times.)
The church was located just across the street from the family home. Pier Giorgio could view the bell tower from his bedroom. A mosaic on the side of the church features St. John Bosco and Blessed Pier Giorgio Frassati. Downstairs, both a youth area and small chapel are named in his honor.
