This Roman Colosseum rises above the entire city of El-Jem, so it's easy to spot. Tourists can walk through the chambers where lions were kept and see the stages where gladiators performed. Executions were also customary in El-Jem 2,000 years ago. The floor was once moveable, an amazing technological feat for the time period.
The $4 admission allows entrance into the museum and ruins. Locals can enter for free. The museum is a short walk from the train station, south toward Sfax. It isn't nearly as impressive as the Bardo but hosts some beautiful mosaics nonetheless.
