The Sudarium of Oviedo, or Shroud of Oviedo, is a bloodstained piece of cloth measuring (33 x 21 inches) kept in the Cámara Santa of the Cathedral of San Salvador, Oviedo, Spain. The Sudarium (Latin for sweat cloth) is thought to be the cloth that was wrapped around the head of Jesus Christ after he died as described in John 20:6-7.
