Rome’s Ancient Arch of Constantine Has Been Struck by Lightning

During a storm on September 3, lightning struck Rome’s Arch of Constantine, chipping the structure’s marble surface. The 1,700-year-old arch and its neighbor, the Colosseum, were two of several sites affected by the thunderstorm, which produced 2.36 inches of rain in less than an hour, per CNN’s Barbie Latza Nadeau. Usually, the city sees a similar amount over the entire month of September.

“A lightning strike hit the arch right here and then hit the corner,” a tourist at the site told Reuters’ Alberto Lingria. “We saw this fly off,” the tourist added while pointing to a fallen block of stone.

Finished in 315 C.E., the Arch of Constantine is one of Rome’s three surviving ancient triumphal arches, each erected to honor a person or event. This arch commemorates Constantine I’s 312 victory over the emperor Maxentius. That same year, Constantine devoted himself to Christianity—the first Roman ruler to do so.

The fierce storm also felled two large trees near the Circus Maximus, flooded the Trevi Fountain and flooded the Colosseum’s subterranean tunnels, reports CNN. After lightning struck the arch, staff of the Colosseum Archaeological Park quickly gathered its dislodged pieces and placed them in a secure location, according to a statement from Italy’s Ministry of Culture.

In the days that followed, some tourists stumbled upon additional pieces on the ground.

​​“My American group found these fragments, and we’re handing them over to the workmen,” tour guide Serena Giuliani told the London Times’ Tom Kington on the morning of September 4.

Specialists are now examining the condition of the fragments. Officials say the damage was limited to the monument’s southern side, where unrelated restoration work had started just days earlier, allowing for quick repairs.

At roughly 70 feet tall and 85 feet wide, the Arch of Constantine contains three separate arches, each framed by columns. The intricately decorated structure is adorned with recycled fragments, or spolia, taken from other ancient buildings, including monuments honoring Trajan, Hadrian and Marcus Aurelius.

The arch is also decorated with carvings of Constantine, including a series of reliefs depicting his victorious fight against Maxentius in the Battle of the Milvian Bridge.

In 306, Constantine was leading Roman troops in Britain—then part of the Roman Empire—when his military declared him their emperor. His brother-in-law, Maxentius, also declared himself the emperor around the same time. After years of complex power struggles, the two rulers ultimately faced off in 312 at Rome’s Milvian Bridge, which overlooks the river Tiber. Panels on the Arch of Constantine depict the battle’s conclusion, showing Maxentius’ troops drowning in the river.

The arch’s recent encounter with lightning may have carried spiritual significance for its ancient builders, as “the bolts were believed to be the work of the gods,” per the Times. These spots were sacred for the Romans, who sometimes erected temples at such sites.
