Visiting Mamertine Prison Rome

4.5 (100%) 605 votes

The Mamertine Prison is an infamous ancient prison situated at the foot of Capitoline Hill in Rome, Italy. Originally it was called the Tullianum. At that time it faced imperial fora of Nerva, Vespasian, and Augustus. A bit odd to be considered a monument due to being a prison, this site enjoys a good rank among popular historical attractions in Italy. In classical Rome, jails and prisons were not as common as these days. Criminals were punished in other ways such as execution and exile. Out of the few ancient lock-ups, Mamertine Prison has survived where the Bible’s most hallowed saints were held.

Along with them, the name of the important pilgrim visitors and their persecutors are also added. If you see at the back, there’s an altar having busts of Saint Paul and Saint Peter. The room is a perfect visiting location for those who want to get a closer look at the life of prisoners held here.

4. Alter

A small altar constructed here is one of the most popular highlights of Mamertine Prison. Probably, it’s because this is where St. Peter baptizing his mate prisoners. An extra-sinister air is provided by the upside-down cross hung on the red marble front. This is symbolic of the Cross of St. Peter where he was crucified, like other saints, upside down.

5. The Spring

As you walk next to the altar, you will find a round opening in the floor. This is what gives access to a spring. Since Classical times, this spring has surfaced in the floor.
