Maziqh St continues to the outer reaches of old Ghadames. At the end, turn left where a few twists and turns between walled gardens and mud-brick houses, past Dan Bero and the Dan Bero Coffee Shop. You'll finally reach Ain al-Faras, the site of a deep well that gave birth to the creation myth of Ghadames.
Unesco has recently realigned and reactivated the spring, making it a delightful spot; steps lead down behind the water to an underground reconstruction of the old well and photos of how it once looked.
