In Tunisia, almost all inhabitants believe in Islam, which is state religion. On Djerba, 98 % of the inhabitants are Muslims. Most of them are Ibadites, who form a self-contained, rather conservative group alongside with Sunnites and Shiites. There are Jewish and Christian minorities of 1% per religion. In order to avoid embarrassing situations and as a sign of respect, you should follow some rules when you leave the hotel. Revealing clothes are a no-no! Plunging necklines are okay in your hotel but not outside and you should cover your shoulders and your knees, especially if you intend to visit a mosque and if you don’t wish to stay outside. When entering a mosque, you should not forget to cover your hair as well. There are around 250 mosques on the island of 514 qkm. However, entry is mostly refused to non-Muslims; you can only visit mosques that are not used anymore by Muslims. Furthermore, you will look vainly for alcoholic drinks on the menu in restaurants or in supermarkets. Due to the religion, alcohol is generally not being sold on the island. If you visit Djerba on Ramadan, of course you will not be missing anything at the buffet, but in the presence of Djerbi, who will be fasting, you should renounce the consumption of food or tobacco.
