Castle of Castilnovo in Segovia showcases a compelling blend of medieval Islamic and Christian architecture, with origins possibly dating to the 8th-10th centuries under Muslim rulers before the current structure was built primarily in the 12th century in distinctive Mudéjar style. Located near the village of Villafranca approximately an hour's drive north of Madrid, the fortress features a rectangular plan with six imposing round and square towers constructed from ashlar stone, Mudéjar bricks, and rubble masonry. The castle achieved royal significance when given to King Henry IV of Castile in the 14th century and later housed Joanna the Mad during the 16th century. Declared a National Monument in 1931, the castle now functions as a private estate encompassing 78 hectares of forest watered by a river, where deer and wild boar roam freely.
