Discover Rome's ancient Carcer Tullianum with an entrance ticket, audio guide, and fascinating stories of biblical figures and historical prisoners.

For just $11 per person, visitors gain access to the Mamertime Prison (Carcer Tullianum) in Rome, a site steeped in history and biblical significance. This ticket includes a multilingual audio guide that brings the dark cells and storied halls to life, making it a compelling stop for those interested in ancient Rome, biblical history, or archaeology. The visit is valid for one day, so travelers can choose a time that fits their schedule, but it’s best to arrive 15 minutes early at the Mamertine Prison.
The tour lasts around an hour and provides a self-guided experience, allowing visitors to explore at their own pace. It’s ideal for anyone looking for an affordable, meaningful glimpse into the city’s ancient penal system and early Christian history. However, visitors should note the tour does not include transportation or a dedicated guide, and some reviews highlight issues with the audio guide functioning properly, especially in lower parts of the prison.

The Mamertime Prison stands as Rome’s oldest penitentiary, historically used to incarcerate enemies of the state. Inside, you see the maximum security cells where prisoners awaited execution. Among the most notable inmates are Jugurtha, king of Numidia, and Vercingetorix, the Gaul chieftain defeated by Julius Caesar. The site is also linked to Christian martyrs and the final days of Peter and Paul.
This small museum sits below the churches and ruins built above it, creating a layered history that visitors can sense as they walk through. The site is particularly meaningful for those interested in biblical history, as it is believed to be the place where Peter and Paul lived their last days.

Visitors enter the dark chambers of Carcer Tullianum, where the damp, stone walls evoke the harsh conditions of ancient imprisonment. The multimedia guide offers stories and details about the prison’s architecture and the prisoners’ final moments. Many reviews note that while the small size of the prison makes it quick to tour, it remains impactful.
The audio guide helps illuminate the lives of notable inmates and recounts the biblical stories linked to the site, especially the imprisonment of Peter and Paul. Visitors can expect to see just one room in the prison, which may feel short but meaningful given the site’s historical weight.

The audio guide is included in the ticket price and offers information in six languages. However, some reviews mention technical issues: the app or downloaded content may be difficult to access, with spotty Wi-Fi and bad cell reception in the lower parts of the prison. Visitors are advised to download the guide beforehand and ask for Wi-Fi passwords if needed.
The guide enhances the experience by sharing artistic details and historical context that are not visible on exhibits alone. Still, some visitors find that the guide doesn’t always work well when down in the cells, which can diminish the experience.

You should arrive early to avoid missing the start time, and download the app and guide before arriving. The lack of a guide on-site means the experience is more introspective but requires some independent navigation.
This entrance ticket offers a focused visit to Rome’s oldest prison with exclusive insights into its artistic and biblical connections. Unlike larger attractions like the Colosseum or Roman Forum, it’s smaller and more intimate.
