They found a stone chest during excavation at a 1,350-year-old church, and the chest had a number of relics inside believed to be associated with the crucifixion, a historian at Turkey's Mimar Sinan University of Fine Arts tells the Hurriyet Daily News.
"We have found a holy thing in a chest," she says. "It is a piece of a cross," and they think it's from the cross.
The entire chest is now undergoing lab tests, reports NBC News. Researchers aren't sure who owned the chest, but it was probably a religious person of some importance, and that person apparently believed the cross relic was the real deal.
The lab tests should shed some light on the possibility, though NBC adds a little context courtesy of theologian John Calvin. He once joked that if all the supposed pieces of the cross in the world were collected in one place, "they would make a big shipload."
