A small salvage excavation in ‘Akko exposed the remains of a previously unknown ravelin outwork in the counterscarp of the Ottoman-period fortifications—a previously unknown military feature—which cut through earlier Crusader and Hellenistic layers. Ravelins are known components of city fortifications in Europe from the late sixteenth and seventeenth centuries, continuing in use in the nineteenth century. In ‘Akko, it seems that the construction of the ravelin was not completed.
