The kasbah crowns the highest point of Béja, a steep climb above the medina. Built and rebuilt by successive rulers — Byzantine, Aghlabid, Hafsid, Ottoman, French — it now stands as a quiet ruin with thick walls and corner bastions, used in modern times as a military barracks and not always open to visitors. Even from outside the gates, the location explains itself: the kasbah commands a 360-degree view over the surrounding wheat fields and on a clear day you can see all the way to the Medjerda valley.
The walk up through the old town is part of the experience. Steep narrow lanes lined with whitewashed houses lead up past the Great Mosque to the citadel walls. If access to the kasbah itself is restricted, the terrace just below offers nearly the same view, and the locals are used to visitors making the climb just for the panorama.
