The Colosseum in Rome will remain closed to the public on Thursday following the death of a 22-year-old worker. Andrea Moretti, a rope-access worker, fell to his death on the night between Tuesday and Wednesday while installing a new lighting system for the historic site. Emergency services were called to the scene but could not revive Moretti. Authorities are investigating the incident to determine the cause of the fall. The Colosseum, a UNESCO World Heritage Site, is one of the most iconic landmarks in Rome and attracts millions of visitors annually. The closure is expected to last at least until further safety assessments are completed. The incident has raised concerns about workplace safety in high-risk maintenance jobs. Moretti’s family has not yet commented on the tragedy.
