Castle of Sagunto – Spain
Located in the northern part of Valencia province at the Sierra Calderona foothills. The walls of the ruined old fortress are nearly 1 km (over 1/2 mile) long and spread over the hillside with sweeping views over the Mediterranean coast and the town of Sagunto. The castle was built over several centuries and thus shows the evidence of Iberian, Carthaginian, Roman as well as Moorish occupation.
