Mamertine Prison (Tullianum) Entry Ticket

Visit Mamertine Prison with a ticket—explore its two subterranean cells, ancient dungeon, and sacred altar beneath the church of San Giuseppe dei Falegnami.

The Mamertine Prison, or Tullianum, represents one of Rome's most poignant historical sites, steeped in both legend and documented history. Located at the foot of the Capitoline Hill, near the Roman Forum, this ancient prison is believed to have been constructed as early as the 7th century BC. Its primary function was to house enemies of the state, those awaiting trial, or those sentenced to death. The prison consists of two chambers: an upper chamber and a lower, more dismal cell. Over the centuries, the Mamertine Prison has become strongly associated with the imprisonment of Saint Peter and Saint Paul, who, according to Christian tradition, were held here before their eventual martyrdom in Rome. This connection has transformed the site into an important pilgrimage destination, drawing visitors interested in both its historical and religious significance. Exploring the Mamertine Prison offers a unique opportunity to reflect on the themes of justice, faith, and the enduring legacy of ancient Rome.
