The church is famous for placing the Turin shroud on the back of the palace. The shroud is a linen cloth that resembles a face. It is said that when Jesus died after crucifixion, he was wrapped in this linen, which clearly records the face of Jesus because of his blood. Its authenticity is displayed every four years. There are replicas in the church, leaving aside the debate over its authenticity and its blood traces as if they were Jesus.
