This sprawling fortress, and one time bastion of government power, whose buildings and courtyards cover over 13,000 square meters, opened to the public in 1988. Walking around the castle, the city’s history gradually unfolds with the cells of former prisoners, the rooms occupied by a succession of Turkish rulers and the Spanish courtyard all open to the public. The most impressive aspects of the castle, though, are its forbidding façade and the Jamahiriya Museum (see next listing).
