El-Jem is a small town in the middle of the desert. We passed there by train from Sousse, and were impressed by the sight of the colosseum sprouting out of nowhere! The Colosseum is superb! It is indeed much better preserved than that of Rome. And the museum nearby having Roman mosaics and statues is also well kept. A must-see site! We then got back to Sousse by using the Luage system - cheap and well organised.
