The attractive town of Castellón de la Plana, chief town of its province, lies in a fertile plain, the Huerta de la Plana, and is a center of the trade in oranges, large quantities of which are shipped from the port of El Grao de Castellón, to the east of the town on the beautiful Costa del Azahar (
"Orange-Blossom Coast"). Castellón was one of the last strongholds of the Republicans in the Spanish Civil War and as a result was largely destroyed, so that it has preserved very few old buildings and presents a predominantly modern aspect.
