This traditional oasis village, named a World Heritage Site, was first populated by ancestors of the Tuareg people and later became the southernmost outpost of the Roman Empire. Today, the old town is for the most part no longer inhabited, but its fascinating collection of winding, covered streets, mud-brick walls and whitewashed houses and mosques are still being preserved. The House Museum provides a good example of how local architecture met the needs of the harsh environment. Also nearby is a cool, inviting lake. Ghadames marks the southern limit of civilization before the terrain is taken over by the sands of the Sahara. 350 mi/585 km southwest of Tripoli.
