Castillo de Montizón, located in Villamanrique, Ciudad Real, is a 13th-century medieval fortress built under the auspices of the Order of Santiago, specifically during the mastership of Pelayo Pérez Correa (1242–1275). Strategically positioned near the Guadalén River, the castle controlled vital trade routes connecting the Campo de Montiel region with the kingdom of Jaén. The fortress achieved historical prominence through its association with the celebrated poet and military commander Jorge Manrique, who served as its commander and participated in a notable 1467 siege. The castle's name became forever linked with the founding of the town of Villamanrique, granted as a reward to Manrique's family. Today, privately owned and substantially preserved, the fortress retains sections of walls and towers sufficient to convey its medieval military significance while remaining accessible to history enthusiasts.
