Technically the name of the stadium is Giuseppe Meazza, but until 1979 it was called San Siro (name of the district of Milan where the stadium is located), almost everyone still calls it "San Siro". I remember an Inter season ticket campaign called "See you at San Siro" and some old Milan tickets with the writing "Giuseppe Meazza", both names, are in fact interchangeable for the majority of fans and even for the two clubs who often use them alternatively or together (Stadio Giuseppe Meazza in San Siro)
