In fourth century AD, Constantine the Great, along with his Mother, Helena, built the Church of the Holy Sepulture. The cross with the crucified Christ hovers above the site where Jesus was crucified. In the bed-rock (beneath the altar) is a large crack caused by the earthquake when Jesus gave up his spirit.
Matthew 27:46, 50
And about the ninth hour Jesus cried out with a loud voice, saying, "Eli, Eli, lama sabachthani?" that is, "My God, My God, why have You forsaken Me?" ... And Jesus cried out again with a loud voice, and yielded up His spirit. (NKJV)
