The Tullianum comes with ancient Roman myths of the great St. Peter, baptizing fellow martyrs at the foot of the spring, this created a devotion that attracted pilgrimages, even to this day.

Did you know

  • As a means of getting the martyrs inside the prison, they simply dropped them into their cell through a hole in the ceiling. 
  • The Carcer Tullianum was for a long time the only public prison in ancient Rome. it was reserved for important state prisoners, more often than not they have put in there prior to their execution.
  • There is a Roman legend that states St Paul and St Peter were both imprisoned there before they were executed, to this day it is unknown as to whether it's in fact true or myth
  • Another legend is that the spring found in front of the altar in the Tullianum was flooded by St. Peter so that he could baptize his fellow prisoners and guards.
  • The cross found on the alter is the wrong way up because it is believed St Peter asked to be crucified upside down so that he wasn't emulating christ. 

Things to see

Tullianum
The Tullianum, also known as the circular lower room, is the cell where the prisoners were thrown into before execution. The altar that is backed with the belief that St Peter baptized his fellow prisoners is situated at the back. 

Carcer
Also known as the upper room, has a plaque mounted to the wall displaying all the most celebrated prisoners. Plus you'll find a hole in the floor that is now covered up for safety reasons - the hole falls directly into the Tullianum, this was the method in which they dropped the prisoners into the cell. 

Alter
The small altar and upside-down cross found at the back of the cell symbolizes St Peters's execution, which is accompanied by the bars that he was supposedly chained to.
