Because of this report in Archaeology (July/August 2017):
“The barracks were abandoned and completely forgotten in the third century A.D., when the Aurelian Walls were built to protect Rome against attacks,” says Rea. Now, after more than 1,700 years spent in oblivion, the garrison is poised to return to its original hustle and bustle—but not without precautions being taken. Project architect Paolo Desideri says, “The new line requires us to excavate to a depth of 130 feet, so the entire ancient Roman site will be moved and stored safely. Later, the barracks will be replaced at their original depth.” Passengers catching a train will be able to see the barracks through a large glass window. Desideri explains that the Aurelian Walls will also be exposed, so commuters can have the same view that people had in antiquity.
I do realize this has been done before, but it just sounds so interesting.
