Scientific testing at what is believed to be Jesus’s tomb dates material there to the fourth century, supporting traditional beliefs surrounding the site, an expert involved in the study said on Tuesday.

The study offers no further evidence whether or not Jesus was actually buried at the site in Jerusalem, but was consistent with the historical belief that the Romans built a monument there some 300 years after his death.

It is the first time such testing has been carried out at the site, located at what is now the Church of the Holy Sepulchre and encased in an elaborate shrine, or edicule.

The tests on mortar at the site were done in connection with recent restoration work, which saw the cave where Jesus is believed to have been buried opened for the first time in centuries.

Antonia Moropoulou, chief scientific coordinator of the restoration works, said the testing was consistent with historical beliefs that the Romans built a monument at the presumed tomb during the era of Constantine the Great, circa 326.
