A 2,300 year old aqueduct was just uncovered in Rome while working on a new Metro line.  The aqueduct was found 17 to 18 meters below the Earth’s surface.  The use of concrete bulkheads allowed them to be working that far below the ground.  At this depth in the Earth, archaeologists have uncovered a sequence of stratigraphy from the Iron Age that includes this aqueduct and other structures that show evidence of what ancient Romans ate and what animals they had.
