It's Good Friday, the day that Christians believe Jesus was crucified. Jerusalem's Old City is crowded with the faithful, retracing the steps of Jesus along the Via Dolorosa -- the Way of Suffering -- to the Church of the Holy Sepulcher, where Christians believe he was crucified.

But they're all taking the wrong route, according to Israeli archaeologist Shimon Gibson. In a new book, titled "The Final Days of Jesus," Gibson says he has found the location of Jesus' trial, where Pontius Pilate, the Roman governor, condemned him to death by crucifixion.

Traditionally it is believed that the trial took place at the Antonia Fortress, outside the Temple Mount, near Lion's Gate. But Gibson believes the trial was actually conducted in an area just outside what is now the western wall of the Old City.
