Castell de Morella crowns an ancient walled city atop a hill in Castellón, built by the Moors atop an Iberian-era rock foundation. The fortress features extraordinary defensive architecture: 2.5 kilometers of walls punctuated by fourteen towers and six gateways, plus notable structures including the Governor's Palace, medieval prisons, a parade ground, and the Celoquia tower. The castle played significant roles during the Napoleonic and Carlist wars, and witnessed pivotal figures like El Cid and Jaume I. Today, visitors can freely explore this extensively fortified site that dominated medieval Valencian strategy.
