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. It 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.

The origins of the shroud and its image are the subject of intense debate among scientists, theologians, historians and researchers. Scientific and popular publications have presented diverse arguments for both authenticity and possible methods of forgery. A variety of scientific theories regarding the shroud have since been proposed, based on disciplines ranging from chemistry to biology and medical forensics to optical image analysis. 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.

Turin (Italian: Torino, pronounced [toˈriːno] ( listen); Piedmontese: Turin, pronounced [tyˈɾiŋ]; Latin: Augusta Taurinorum) is a city and major business and cultural centre in northern Italy, capital of the Piedmont region, located mainly on the left bank of the Po River and surrounded by the Alpine arch. The population of the city proper is 909,193 (November 2008) while the population of the urban area is estimated by Eurostat to be 1.7 million inhabitants. The Turin metropolitan area is estimated by the OECD to have a population of 2.2 million.

The city has a rich culture and history, and is known for its numerous art galleries, restaurants, churches, palaces, opera houses, piazzas, parks, gardens, theatres, libraries, museums and other venues. Turin is well known for its baroque, rococo, neo-classical, and Art Nouveau architecture. Much of the city's public squares, castles, gardens and elegant palazzi such as Palazzo Madama, were built in the 16th and 18th century, after the capital of the Duchy of Savoy (later Kingdom of Sardinia) was moved to Turin from Chambery( nowadays France) as part of the urban expansion.
