After admitting to illegally entering the Colosseum, they faced a €800 (NZ$1290) fine.
According to a spokesperson for Rome's police force, the law-breakers were outed by citizens walking by.
"During the early hours of Monday morning some people noticed two young men drinking beer in the Colosseum, facing outwards on the second level," the spokesperson told CNN.
"They alerted a police car nearby, which then stopped the two young men on Via dei Fori Imperiali."
As bad behaviours goes, sneaking in for a morning beer isn't the worst the Colosseum has endured.
In 2014, a Russian tourist had to pay up $32,200 for carving the letter "K" into the ancient walls. If that wasn't warning enough, a 14-year-old German student similarly carved his initials into the walls in 2019.
The Colosseum was opened in 80 A.D and hosted many bloody gladiatorial fights for the enjoyment of up to 50,000 spectators.
Back then, punishment for sneaking into the theatre could have been battling a wild beast. A fate that makes a monetary fine seem relatively light.
