An aqueduct dated to the 3rd century BC, being the oldest in the city, was discovered in Rome, Italy, during construction works of the C metro line in the area of Piazza Celimontana.
The unearthed structure measures 32 metres in length and is located nearly 20 metres underground. The ruins of the structure were unearthed during work on a ventilation shaft. A ten-metre section of aqueduct has now been dismantled block by block, catalogued, and piled up back on the surface. There are plans to to reassemble it where the public can see it. Iron Age tomb with grave goods was also found during the construction in the vicinity. The grave goods include two bowls, from the late 10th-early 9th century BC. The tomb was found at the depth of 18 metres .
