was the Roman state prison. The carcer
was used primarily for detention, although it was also used for some executions. The underground section of the carcer
was called Tullianum, perhaps having been built by Servius Tullius. Ancus Martius is also credited with building it and the name may derive from a word for spring, tullus. The seven-meter in diameter Tullianum was accessible through a hole in the roof.
