The Cathedral of Saint Mary of the Assumption in Coria preserves a linen cloth that a long-standing tradition identifies as the tablecloth used at the Last Supper of Jesus with his apostles.
This Cathedral had already become a destination for pilgrimages at least since the late Middle Ages. This is attested by a papal bull of Benedict XIII, issued in Genoa on July 16, 1405, and another of Eugene IV, issued in Rome on October 10, 1444. Both documents refer to chests containing relics and to a Lignum Crucis that attracted numerous faithful on May 3, the Feast of the Cross.
Although there is no documentary evidence of its origin, a canonical visitation by Bishop Juan Roco Campofrío (1632–1635) mentions the tradition that the relics were brought from Rome by a bishop. This information could correspond either to a transfer prior to the 8th century or, after the reconquest of the city, to the time of the first bishop Íñigo Navarrón (1142–1152) or his successor, Suero (1157–1168).
