A severe drought across Europe has lowered river levels, exposing historical artifacts. In Rome, the Tiber's receding waters have revealed the remains of the Pons Neronianus, or Nero's Bridge, near the Vatican. The bridge, dating from the 1st century AD, was likely built by Caligula and later associated with Nero. Its emergence has drawn tourists and highlighted the region's water crisis, with the river's flow dropping below 80 cubic meters per second, half the historical July average .
In Serbia, the low waters of the Sava River have uncovered the wreck of the 'Slovenian', a 54-meter steamship built in 1913 that sank after hitting a German mine in 1945. Local media have dubbed it the 'Titanic of the Sava' .
The drought has also exposed other relics, such as German warships and military equipment, while affecting navigation, energy production, and agriculture. Copernicus satellite data indicate that many rivers have reached historic lows, with forecasts of continued dry conditions through September .
This is not the first time the bridge has appeared; it was used for centuries to moor mills. Its current visibility offers a rare opportunity for visitors . The situation echoes ancient Rome's water management challenges, as documented by engineer Sextus Julius Frontinus in the 1st century AD, who combated illegal water diversions .
