Extreme Heat in Rome Reveals 2,000-Year-Old Nero's Bridge

Record-breaking heat and prolonged drought in Rome have caused the Tiber River's water level to drop significantly, uncovering the remnants of Nero's Bridge, a structure estimated to be nearly 2,000 years old. The river's flow has decreased to below 80 cubic meters per second, roughly half the average for this time of year, exacerbating a serious water crisis in the region.

Giovanni Giganti, Rome's Civil Protection Coordinator, described the situation to the Associated Press, noting that while winter rainfall is usually abundant, it is often followed by extended dry periods. This pattern has led to the drastic reduction in the Tiber's water levels.

The bridge, known as Pons Neronianus, is thought to have been constructed around 39 AD during the reign of Emperor Caligula and later named after his nephew, Emperor Nero. Historical accounts suggest it connected the Campus Martius area in ancient Rome to the Circus of Nero, believed to be the site where Saint Peter was martyred. Today, this area encompasses landmarks like the Spanish Steps, Piazza del Popolo, and St. Peter's Basilica.

Normally submerged, the large stone blocks of Nero's Bridge are now visible from the Sant'Angelo Bridge near the Vatican. This unusual exposure provides archaeologists with a rare opportunity to examine the 2,000-year-old structure up close. The receding waters have also revealed other items, including electric bikes, scooters, refrigerators, and even a car, further up the river. The bridge's ruins were last seen during a similar drought in 2022.
