Sufetula ruins are quite big and some highlights as pictured but overall I found they aren't unique enough to be inscribed. Haven't we got enough Roman ruins already, better, more unique and really worth visiting.

The ticket office is across the entrance by the way, so if you just walk in they'll follow you to buy a ticket. Somehow they only do this to foreign guests which seems a little discriminating, and while I don't care about the difference in entrance ticket price the fact they can just waltz in but I get chased after with a buggy because there was nobody at the entrance made me feel like I dislike the place too...

And seeing that I spent most of the review ranting about something else I'll say that the arch is quite nice and you can see plus take pictures of it from outside the walls, but seeing that you came all the way I suppose you are entering the site proper.
