According to Christian tradition, the True Cross was discovered in 326 by Saint Helena, the mother of the Roman Emperor Constantine the Great, during a pilgrimage she made to Jerusalem. The Church of the Holy Sepulchre was then built at the site of the discovery, by order of Helena and Constantine. The church was dedicated nine years later, with a portion of the cross. One-third remained in Jerusalem, one-third was brought to Rome and deposited in the Sessorian basilica Santa Croce in Gerusalemme (Holy Cross in Jerusalem), and one-third was taken to Constantinople to make the city impregnable.

The date of the feast marks the dedication of the Church of the Holy Sepulchre in 335.
