The Church of the Holy Sepulchre is located in the Old City of Jerusalem and considered the holiest Christian site in the world. It stands on a site between Golgotha and Calvary, believed to be where Jesus was crucified, and the tomb, or sepulchre, where he was buried.
The site remained buried until Emperor Constantine converted to Christianity and commissioned numerous churches to be built throughout the Holy Land. In the course of the excavations, Constantine's mother St. Helena, is said to have discovered the True Cross near the tomb. It is said she discovered three crosses - those of the two thieves and that of Christ. To discern the one belonging to Christ, a sick man was brought to touch to each one, and he was miraculously healed by one of them.
Constantine's builders dug away the hillside to leave the rock-hewn tomb of Christ isolated and with enough room to built a church around it.
