Castellnovo Castle

Castellnovo, Spain, Spain

---

Castellnovo Castle, located in the village of Castellnovo in Castellón province, Valencian Community, Spain, traces its origins to Roman times as part of Segorbe's defensive network before major reconstruction by Muslims and later Christians after James I's 1233 conquest.

The fortress boasts a rectangular plan with six towers—three round and three square—featuring a central curved portal, ashlar machicolations, ribbed vaults, pointed arches, and Renaissance details from 15th-century renovations under Beatriz de Borja, blending Mudéjar, Gothic, and transitional styles.

Well-preserved amid scenic Alto Palancia terrain, this Bien de Interés Cultural offers visitors insights into layered Iberian military history through its courtyard, defensive features, and noble heritage tied to the Catholic Monarchs.
