One of the most intriguing and sinister places to explore in Rome is the Carcere Mamertino, also known as the Mamertine prison. This ancient prison, located next to the Roman Forum, is shrouded in dark history and legend. According to popular belief, it was in this very prison that the apostles Peter and Paul were held captive before their martyrdom. Although the evidence for this is not concrete, the memory of these influential figures is commemorated with an altar within the prison. The Carcere Mamertino consists of the Tullianum, which served as a death row where prisoners were executed. Today, visitors can explore the ancient ruins of the prison, including two cells and part of the original facade. The name ‘Mamertine’ is thought to be derived from the Latin ‘Mamertinus’, a reference to the nearby altar of the god of war, Mars. While the physical structure of the prison may not be grand, its chilling history is what draws visitors to explore its depths. To visit the Carcere Mamertino, consider booking tickets online for a comprehensive experience that also includes access to the Colosseum, Roman Forum, and Palatine Hill. The ancient Carcere Mamertino is a must-see for history enthusiasts and those intrigued by the darker side of Rome’s past.
