A medieval tower near the Roman Forum in central Rome partially collapsed on Monday during renovation work, leaving at least one worker seriously injured, according to Italian media reports.
Firefighters rushed to the Torre dei Conti, using a mobile ladder to reach the upper floors where three workers were rescued. One worker remained trapped inside the structure, Corriere della Sera reported.
During the rescue effort, another section of the centuries-old tower gave way, sending up a large cloud of debris. Firefighters on the ladder managed to descend safely before the additional collapse occurred. Authorities were still determining if more people were injured.
The Torre dei Conti, built in the early 13th century by Pope Innocent III as a family residence, has endured several structural failures throughout its history. It was first damaged by an earthquake in 1349 and suffered further collapses in the 17th century.
Rome Mayor Roberto Gualtieri and Culture Minister Alessandro Giuli visited the site following the incident.
