Pier Giorgio Frassati's mortal remains were placed in the Pollone cemetery in 1925 and remained there until 1990 when, upon his beatification, they were moved to the Cathedral of St. John the Baptist in Turin. Pier Giorgio's mother, Adelaide, an accomplished artist, painted the walls of the crypt with reproductions of famous scenes. Upon the death of Pier Giorgio's sister Luciana in October 2007, her remains were placed in the exact spot once occupied by Pier Giorgio.
