The Sudarium of Oviedo, or Shroud of Oviedo, is a bloodstained cloth, measuring c. 84 x 53 cm, kept in the Cámara Santa of the Cathedral of San Salvador, Oviedo, Spain. The Sudarium (Latin for sweat cloth) is claimed to be the cloth wrapped around the head of Jesus Christ after he died, as mentioned in the Gospel of John (20:6-7). The small chapel housing it was built specifically for the cloth by King Alfonso II of Asturias in AD 840; the Arca Santa is an elaborate reliquary chest with a Romanesque metal frontal for the storage of the Sudarium and other relics. The Sudarium is displayed to the public three times a year: Good Friday, the Feast of the Triumph of the Cross on 14 September, and its octave on 21 September.
