One of the few pieces of Renaissance architecture in Baroque-dominated Turin, this otherwise uninspiring 15th-century cathedral is famous as the resting place of the Turin Shroud. The Turin Shroud is said to be the piece of fabric in which Christ was wrapped when he was taken from the cross—and to which his image was miraculously affixed. The image on the cloth is of a bearded face—remarkably similar to the depiction of Christ in Byzantine icons—and a body marked with bloodstains consistent with a crown of thorns, a spear slash in the rib cage, nail holes in the wrists and ankles, and scourge marks on the back from flagellation. Regardless of scientific skepticism, the shroud continues to entice hordes of the faithful to worship at its chapel in the Duomo di San Giovanni Battista (it's the last one in the left-hand aisle). The linen cloth is preserved in an aluminium casket specially manufactured by an Italian aerospace company in the temperature-controlled, air-conditioned Cappella della Sacra Sindone and closed off from human contamination with bulletproof glass. The shroud’s casket is adorned with a crown of thorns. To learn all about the history of the shroud, head for the Museo della Sidone (Via San Dominico 28).  Note that the shroud is typically taken out for public viewing every few years, most recently in 2015; the decision to do so is usually made by the reigning pope. Log on to to find out when the shroud will next be taken out and displayed; advance reservations are required to see the shroud during these brief public displays.
