A historic Rome tower partially collapsed during renovations, injuring workers and raising safety concerns.

A section of the 13th-century Torre dei Conti in central Rome partially collapsed Monday during renovation work, injuring at least one worker critically and trapping another. Firefighters rescued three others, but a second collapse forced them to retreat, delaying the rescue. The tower, built by Pope Innocent III, had previously been damaged by earthquakes and collapses. Rome’s mayor and Italy’s culture minister visited the scene, and an investigation into construction safety has begun. The site remains closed, and concerns have grown over the safety of historic structures under restoration.
