Israeli archeologists announced Sunday that the largest underground quarry in the Holy Land has been discovered and it dates back to the time of Jesus and contains Christian symbols that are etched into the walls.

"The 'foot' structures that we found in the Jordan valley are the first sites that the People of Israel built upon entering Canaan and they testify to the biblical concept of ownership of the land with the foot," said archaeologist Prof. Adam Zertal of the University of Haifa, who headed the excavating team that exposed five compounds in the shape of an enormous "foot", that it were likely to have been used at that time to mark ownership of territory.
