Borj el-Kebir by Willettsworld
This massive square fortress, built in 1595, is commandingly situated on the highest point on the peninsula. It was built on the site of a palace built by Mahdia's founder, Obaid Allah el Mahdi in the 10th century. In the courtyard of the fortress is a small mosque. In the masonry of the tower at the southwest corner are two reliefs which are believed to have come from an earlier building.
