The relics of Santiago de Compostela are believed to be the remains of Saint James the Greater, one of Jesus' apostles. These relics are housed in the Santiago de Compostela Cathedral in Galicia, Spain, a significant pilgrimage site for Christians. The discovery of these relics in the 9th century led to the establishment of the Camino de Santiago, a network of pilgrimage routes across Europe. Pilgrims visit the cathedral to pay their respects and seek spiritual fulfillment. The relics are kept in a silver urn, which is displayed during special religious ceremonies. This tradition has made Santiago de Compostela a central point of Christian pilgrimage for centuries.
