Archaeologists in Turkey who were working at an ancient church think they have found a piece of the world's most famous cross, the one used to crucify Jesus.

A historian at Turkey's Mimar Sinan University of Fine Arts tells the Hurriyet Daily News, that they found a stone chest during excavation at a 1,350-year-old church, and the chest had a some relics inside that they believe to be associated with the crucifixion.

NBC has reported that the chest is  undergoing lab tests. Researchers aren't sure who owned the chest, but they believe 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."
