Tamerza, Tunisia's largest mountain oasis, is a striking blend of natural beauty and historical intrigue. Once a Roman outpost known as Ad Turres, it features dramatic canyons, cascading waterfalls, and an abandoned old town left deserted after a devastating flood in 1969. Nestled near the Algerian border and close to the salt lakes, the oasis thrives on fresh water from the surrounding hills. Visitors can explore its rugged terrain, enjoy its springs, and take in the remnants of a town steeped in both history and resilience.
