3Timbuktu, Mali

There’s always been a mythical air about this ancient Saharan town, which was one of the most important seats of Islamic learning for centuries. But this UNESCO World Heritage Site has since come under attack by Islamist rebels, and tourist numbers to Timbuktu have plunged.   

Its significant place along Africa’s major trade routes gave Timbuktu its wealth, and salt traders still travel this route in spite of the dangers. Before the Islamist insurgents appeared, the town was the focus of fighting from its Tuareg population.
