The Shroud of Turin or Turin Shroud (Italian: Sindone di Torino, Sacra Sindone) is a linen cloth bearing the image of a man who appears to have suffered physical trauma in a manner consistent with crucifixion. It is kept in the royal chapel of the Cathedral of Saint John the Baptist in Turin, northern Italy. The image on the shroud is commonly associated with Jesus Christ, his crucifixion and burial. The origins of the shroud and its image are the subject of intense debate among scientists, theologians, historians and researchers. The Catholic Church has neither formally endorsed nor rejected the shroud, but in 1958 Pope Pius XII approved of the image in association with the Roman Catholic devotion to the Holy Face of Jesus.
The image on the shroud is much clearer in black-and-white negative than in its natural sepia color. The negative image was first observed in 1898, on the reverse photographic plate of amateur photographer Secondo Pia, who was allowed to photograph it while it was being exhibited in the Turin Cathedral. In 1978 a detailed examination was carried out by a team of American scientists called STURP. They found no reliable evidence of forgery, and called the question of how the image was formed "a mystery".
