The train was super-comfy compared to being stuffed into a louage, even though I've certainly been on nicer trains.
Around noon, I disembarked in El Jem. I could see my destination towering over the street at the far end of town.
That's it. That's why I stopped off here to look around during my train trip from Gabes to Tunis.
I headed to the ticket office, paying my entry fee and leaving my bag at the ticket office. I spent an hour wandering around. Photos are here.
