The Shroud of Turin or Turin Shroud (Italian: Sindone di Torino, Sacra Sindone or Santa Sindone) is a length of linen cloth bearing the negative image of a man who is alleged to be Jesus of Nazareth. It is kept in the royal chapel of the Cathedral of Saint John the Baptist in Turin, Piedmont, northern Italy. The cloth itself is believed by some to be the burial shroud that Jesus was wrapped in when he was buried after crucifixion. It is first securely attested in 1390, when a local bishop wrote that the shroud was a forgery and that an unnamed artist had confessed. Radiocarbon dating of a sample of the shroud material is consistent with this date.
