 | 2 ancient Roman sarcophagi were unearthed close to Rome’s football stadium in 2017. The marble coffins boast elaborate bas-reliefs and were probably the final resting place of the children of a wealthy Roman family. Discovered by chance when an energy utility company started digging in the area, they appear to date from the third or fourth century AD. |  |
Ancient artifacts are routinely discovered beneath the streets of Rome during construction and maintenance work.
