Ancient Wall Discovered in Jerusalem

A large, ancient wall has been uncovered in Jerusalem. Check out the story here.

About the wall: it's said to be 3,700 years old, and stood "8 meters (26 feet) high."

"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."

Amazing.
