Ajim, Island of Djerba, Tunisia
The cantina where Luke and Obi-Wan get stopped by sandtroopers is in the middle of the island town of Ajim. The building, once a bakery, went out of use and can be hard to find.
The GPS coordinates are 33°43’26.69″N, 10°44’59.95″E.
Obi-Wan’s home is easier to find, ironically located right on the Mediterranean Sea and much more beautiful than its desolate film locale. A lovely spot for a building that’s used by fishermen as a storeroom.
