Built in the lst century AD, outside the city, the Carthage amphitheatre was considered one of the largest of the Roman Empire. In their descriptions, medieval chroniclers refer to imposing structures with high arches.

Today it lies a short distance from the roadside and all that remains is an oval shaped arena, 65m long by 37 wide, with at each end, the openings to let in the wild animals. The most famous martyrs to have died there, Saint Perpetua and Saint Felicity, were martyred for their faith in 203.
