About Mamertine Prison
The Mamertine Prison in Rome, also known as Carcere Mamertino, is an ancient prison thought to date back to perhaps as early as the seventh century BC. The Romans continued using the Mamertine Prison throughout the Republican and Imperial eras as late as the fourth century AD, with executions also taking place there.
Christian legend says that the Mamertine Prison was the site where Saints Peter and Paul were incarcerated. According to these accounts, Peter managed to create a spring in his cell, allowing him to perform baptisms on his cellmates and guards.
Today, the remains of the Mamertine Prison are found under the church of San Giuseppe dei Falegnami near the Roman Forum. Dark and dank, the dungeons are accessed via a winding staircase and offer a glimpse into the horrors experienced by criminals of Ancient Rome.
It is also worth noting that, near the Mamertine Prison (some say right next to it) would have been the location of the Gemonian Stairs, also notorious as a site of executions in Ancient Rome.
