The Arch of Constantine in Rome, one of the city's triumphal arches, has been damaged in a violent thunderstorm.
Fragments from the ancient structure – built in 315 – broke off when it was struck by lightning. Exactly how extensive the damage is unclear, but the pieces were immediately collected from the street and work to restore the arch began.
The Arch of Constantine was erected in memory of Emperor Constantine's victory over Maxentius at the Pons Milvius bridge in 312. The 20-meter-high arch is located between the Colosseum and the Palatine in Rome.
The thunderstorm also knocked down trees and flooded streets in the Italian capital.
