Archaeologists announce "sensational discovery" on Rome's Coelian hill.

The unearthing of a Roman aqueduct has been announced by Rome archaeologists who describe it as a "sensational discovery of enormous importance, as it is almost certainly the most ancient Roman aqueduct, dating from the third century before Christ”.

The 32m-long section of the 2,300-year-old aqueduct was discovered in Piazza Celimontana in late 2016, during construction work for Rome's Metro C, in front of the Celio military hospital.

Since construction began in 1990, progress on the capital's third metro line has been hampered by funding overspends, lengthy delays and the regular discovery of archaeological remains underground which have led to the abandonment of several stations in central Rome.

The Metro C station in S. Giovanni, which will become the 22nd station on the 18-km driverless line, will display archaeological finds when it opens in autumn.
