"In Guellala: Ali Berbere" Ile de Jerba Off The Beaten Path Tip by Kid-A

Ali Berbere is an old man who makes pottery and is happy to give you a history (in French) of pottery and the making of olive oil on Djerba. This history he explains of how they made olive oil in former times is especially interesting.

He lives in Guellala, a village on the southern end of the island. The town is sort of famous for pottery, in that a lot of the pottery found on the island comes from this town. Ali Berbere is entertaining and accomodating. In the end, you're supposed to give him a Dinar or 2 for his time. You can also buy pottery from him, or help him make some pottery. The building he lives and works in was built in Roman times, he says.

I'm not sure how to describe where he is located. If you want to find him, I imagine asking a local will get you there very quickly. He's well known in the area.
