Sousse

Sousse is a Mediterranean port on the eastern coast of Tunisia. Under the Aghlabids in the ninth century it became an important commercial and military harbor for Ifriqiya. The ribat, a fortified religious building near the old port, watched over the coast; its tower could signal to the ribat of Monastir. The Great Mosque and city walls also date from the Aghlabid period, when Sousse was closely linked with inland Kairouan.
