Built in the 7th century BC, Mamertine Prison is Rome’s oldest prison. 

Known as the Tullianum during ancient times, it is also referred to as the Tullianum Carcer.

It is a small, dark, and cramped place that held enemies of Rome such as captured Kings, conspirators, and even Saints Peter and Paul before the State executed them.

According to legend, a spring of water flowed in Tullianum Carcer so that St Peter could baptize visitors (and two prison guards).

After the site stopped being a prison, it became a holy destination because it had held some of the Bible’s most hallowed saints.

In this article, we share everything you must know before buying Mamertine Prison tickets.

What to expect at Mamertine Prison

The Mamertine Prison consists of two dark underground cells, where Rome’s enemies were imprisoned and usually executed.

Recently built steps take you to the upper level of the prison, which is at the original ground level of ancient Rome. 

The upper room of the prison dates from the 2nd century BC and displays a plaque naming the more famous prisoners and how and when they died.

The second plaque lists the saints and martyrs imprisoned here and their persecutors.

You will also see the busts of Saints Peter and Paul in this room. 

Back in the days when the Mamertine Prison was active, prisoners would be lowered into the lower room through a round opening on the upper room floor. 

Nowadays, visitors take a staircase to get to the lower room.

At the top, visitors can see the stone said to have St. Peter’s head imprint from when he was thrown into the prison.

The lower room, the Tullianum, is circular and has a small altar, with a relief of St. Peter baptizing his fellow prisoners. 

At the altar, you will also see an upside-down cross because St. Peter got crucified upside down.

Don’t miss the column where St Peter and St Paul were tied when they converted two prison guards to Christianity.

You will also see the spring that St Peter was supposed to have miraculously created to baptize people.

History of the Mamertine Prison

The Mamertine Prison was constructed in the 7th century BC under King Ancus.

Builder Servius Tullius built the lower room of the prison, which is why it is also known as Tullianum.

Ancient historian Sallust has written that this part of the prison was 3.6 meters (12 feet) below the ground and was dark and smelly. 

Tullianum was used for the detention and execution of condemned criminals.

The prison was in use until at least the late 4th century AD, after which it became a pilgrim site because of its association with Christian martyrs. 

With time it got the name Mamertinus.

In the 16th century, the San Guiseppe dei Falegnami church got built above the prison.

Mamertine prison’s Christian connection

According to early legends, Saints Peter and Paul were imprisoned in the Mamertine jail by Emperor Nero before their execution. 

It is believed that after being in this prison for some time, both started their journey to martyrdom – St Peter towards the Circus of Nero and St Paul towards the Aquae Salviae.

At St. Peter’s request, he was crucified upside down on the site of the Vatican, and St. Paul was beheaded at Three Fountains Abbey.

Believers say St Paul refers to the Mamertine prison in the Bible (Timothy 4:21) when he urges Timothy to visit him as he did not expect to get out until the following winter. 

Even though there is no actual historical evidence for this, the prison is an important religious site. 

The legend had taken root by the 5th century when the prison started attracting early pilgrims. 

During his stay, St. Peter is known to have caused a spring to miraculously well up in the prison so that he could baptize his fellow prisoners and two of the guards.

However, according to Catholic Encyclopedia, the spring existed long before St. Peter’s incarceration.
