contained in the (). The Holy Chamber is the only surviving portion of the ancient high-medieval complex. It was built to keep such relics and treasures associated with the Asturian monarchy as the Cross of the Angels, Victory Cross, and the Agate Box or Agate Casket. The chief feature of the cathedral is the "Camara Santa", with its venerable relics. Bishop Pelagius relates that the Agate Box, a coffer made by the disciples of the Apostles and containing the most precious relics of the Holy City, was taken from Jerusalem to Africa, and after residing in several locations was finally placed at Oviedo by Alfonso II. In the 16th century, Bishop Cristóbal de Sandoval y Rojas wished to open it, but could not, being overcome with religious fear.
