Then another Roman emperor, Constantine the Great, intervened in either 325 or 326. He was the first emperor to follow the Christian faith and consequently commanded that the pagan temple be demolished. Constantine then had a Christian church built in its place – what we now call the Church of the Holy Sepulchre. And as the new church was being constructed, it’s said that Constantine’s mother, Helena, found Christ’s tomb.
But the church that now stands in Jerusalem is not the same one that Constantine built. It’s on the same site, but the original church was destroyed in 614 when Khosrau II, Emperor of the Sassanids, captured Jerusalem and put the church to the torch.
In 630 yet another Roman emperor, Heraclius, recaptured Jerusalem and restored the church, only for it to be badly damaged once more by earthquakes in 746 and again at the start of the 9th century. A number of fires then further damaged the church in the ensuing decades.
