The Turin Shroud, one of Christianity's most celebrated relics went on to the public display recently for the first time in five years.
The 4.4-metre-long cloth will be on show until 24 June, BBC News reported.
Viewings are free but must be booked. One million people have already signed up. Pope Francis will be among those to view the shroud, during a visit to the northern Italian city on 21 June.
The shroud is displayed in a climate-controlled case for 12 hours a day in Turin's Cathedral of St John the Baptist.
