This Tunisian site on the tentative list is also a multiple site with some accessibility issues. The site's components are: the Bir Oum Ali wall, the Jebel Tebaga wall, the Ksar Ghilane/Tisavar fort, the Ksar Tarcine fort, the Bénia Guedah Esseder fort, and the Bénia bel Recheb fort.

During my preliminary research on Google Map, I had pointed out the wall of Bir Oum Ali, the wall of Jebel Tebaga and the adjoining fort of Bénia Guedah Esseder since Djebel Tebaga is itself part of the site of the indicative list: "The marine Permian of Jebel Tebaga".

Coming from Gafsa to Kebili via the very beautiful P15 and its magnificent oases, we inevitably pass by the remains of the wall of Oum Ali as Zoë has already written, after having passed the deserted checkpoint dozing under the sun that she mentions.

On the other hand, to visit the Jebel Tebaga wall and the fort of Bénia Guedah, which are now nothing more than earthworks, you have to take a track. In Kebili, the owner and manager of the campsite Les Amis du Camping advised me not to go there alone in 42°C heat with a vehicle that is not a 4x4. I followed his good advice and therefore settled for the wall of Oum Ali.

I can't tell you how delighted I was when I stopped on the Jebel Pass at the height of the wall, thinking of the Limes I had visited in Germany, 2,000 km away as the …

We all love more Limes sites. Did you know there was a Limes in Tunisia? Interesting, but not interesting to look at, basically like the rest of the Limes aside of some special section such as Hadrian's Wall. Also I find it hard to believe the Limes in the Sahara was anything useful at the time, but like the Great Wall of China (uhhh I dared to make THAT comparison) it was meant for watchtowers to signal any incoming attack and like thr Greal Wall (yes I said it) it didn't actually work to defend a frontal attack. It was meant to protect trade routes from sub-Saharan countries and ensure goods are taxed.

There are not many places in Tunisia reachable so I picked the Muraille de Jebel Tebaga. The road will lead you right through the pass and there is a military checkpoint just north of the location. The guys there had some chuckles that I wanted to go there but told me it's only 2 more minutes down the road. Blink and you will miss it but the good news is that you can find it on Google maps so you can sort of figure out when to look up the cliffs. You can also find a small dirt road going up a hill to a tower and park there, walking up the hill to the wall. There are more sections on the opposite side as pictured but climbing up there requires extra efforts and I don't …
