Tunis has been Tunisia's capital since the Almohads took it in 1159, reaching its height under the Hafsid dynasty from 1228 as one of the richest cities in the Islamic world. The settlement dates to 698 AD, when a mosque rose beside the ruins of Carthage on the Lake of Tunis. The walled medina, UNESCO-listed since 1979, holds the Zaytuna Mosque among hundreds of monuments. The uprising that toppled Ben Ali and opened the Arab Spring began 300 km south in Sidi Bouzid in December 2010, but crowds on Avenue Habib Bourguiba downtown forced him out that January; the capital is calm day to day now. The dinar cannot be exchanged abroad, so a month here runs mostly on cash drawn locally.
