Over a million people have signed up to see the Turin Shroud, which has gone back on public display, after a five year break. The 14ft long cloth is on display April 19th until June 24th. Viewings must be booked and are free. Some believe the shroud is the burial cloth of Jesus Christ. The shroud is displayed 12 hours a day in the Cathedral of St John the Baptist, Turin, Italy.
