Large elegant cathedral dating from late 15th century, enlarged in the 17th to create the Chapel for the Shroud of Turin. The original shroud is kept safe in a vault and only rarely displayed - visit the nearby Sindone Museum to see a copy. The Chapel was destroyed in a fire in 1997; rebuilding is complete but other restoration continues, eg a new altar is still needed. This Chapel is nowadays accessed as part of a tour of Palazzo Reale and can't be seen from the Cathedral.
