Work on Rome's Metro Line C has been beset by delays due to corruption probes and funding shortages since launching in 2007

And, the recent discovery isn't the only instance in which construction on the city's public transit ran into this kind of obstacle. In 2014, archaeologists found the remainders of an ancient commercial farm near St. John in Lateran Basilica during work on the subway

This agricultural business dated back to the first-century, the researchers estimated.

They also found peach pits, along with well-preserved vestiges of willow and other tree roots and stumps.

As is hoped with the artefacts recently discovered at the Amba Aradam stop, officials at the time planned to incorporate the find into the metro station.
