Rooftop, Ribat of Sousse, Tunisia, 2009. The Ribat in Sousse is thought to have been founded in the 8th century and reconstructed or completed in its current form during the early 9th century, under the Aghlabid dynasty. Although a large number of ribats were built in the region during that period, the Ribat of Sousse is by far the best-preserved.
