Sagunto is a municipality of Spain, located in the province of Valencia, approximately 30 km (19 mi) north of the city of Valencia. The municipality includes three differentiated urban nuclei: Ciutat Vella (Sagunto), Grau Vella and Puerto de Sagunto. More than half of the population lives in Puerto de Sagunto, situated on the Mediterranean Costa del Azahar. The Ciutat Vella is the site of the ancient Iberian and Roman city of Saguntum and a siege in 219 BC which was the trigger of the Second Punic War between the Carthaginians and the Romans. This panorama shows the Ciutat Vella, looking north from the hill on which Sagunto Castle stands.Photograph credit: Diego Delso
