Castellón-Castelló
In the spurs of Sierra Espadán we find Onda, a historic village in the interior of Castellón, which holds an important monumental heritage, and has a long tradition in the production of ceramics.
Inhabited since the times of the Iberians (6th-1st centuries BC), Onda reached its maximum splendour during the Middle Ages. The days the town lived under Arab rule (10th-13th centuries) gave the historic quarter its urban layout, which was declared a Historic-Artistic Site, and a Cultural Object.
