JERUSALEM (CNN) -- An archaeological dig in Jerusalem has turned up a 3,700-year-old wall that is the largest and oldest of its kind found in the region, experts say.
Standing 8 meters (26 feet) high, the wall of huge cut stones is a marvel to archaeologists.
"To build straight walls up 8 meters ... I don't know how to do it today without mechanical equipment," said the excavation's director, Ronny Reich. "I don't think that any engineer today without electrical power [could] do it."
Archaeologist Eli Shukron of the Israel Antiquities Authority added, "You see all the big boulders -- all the boulders are 4 to 5 tons."
