Tamaghza el Gdima is the ruined old village above modern Tamerza. Its houses were built from local stone and mud, so the walls seem to grow out of the hillside rather than sit on it. Doorways open into roofless rooms, lanes narrow between collapsed walls, and from a distance the whole settlement almost disappears into the same ochre tones as the cliffs.
The site is easy to explore on foot, though the ground is uneven and some walls are unstable. Go early or late if you can; in the middle of the day the stone throws back heat. The best views are from the upper edge of the ruins, looking down over the palms and across the dry country toward the Algerian frontier.
