A major infrastructural project near the Vatican is still on track to open in time for Jubilee Year 2025 despite the discovery of important archaeological finds, Rome's mayor said on Friday. The remains of an ancient Roman laundry were unearthed during excavations to build an underpass in Piazza Pia, located between Castel S. Angelo and Via della Conciliazione, the street leading to St Peter's Square.

Archaeologists working on the construction site discovered part of a residential building from the early imperial age, transformed in the second century AD into a fullonica, the ancient Roman equivalent of a dry cleaners.
