The "True Cross" refers to the actual cross upon which Jesus Christ was crucified, according to Christian tradition. It is considered a sacred relic and symbolizes the sacrifice of Jesus for humanity's sins. The True Cross is believed to have been discovered by Saint Helena, the mother of the Roman Emperor Constantine, during her pilgrimage to Jerusalem in the 4th century. Throughout history, fragments of the True Cross have been venerated in various churches and cathedrals, often encased in ornate reliquaries. The cross serves as a powerful symbol of faith and redemption for many Christians, representing hope and the promise of eternal life.
