Castillo del Hierro, also called Castillo de Pruna, rises dramatically on a mountain ridge overlooking the village of Pruna in Sevilla province. Built by the Moors during the 12th-13th centuries on a Celtiberian settlement site, its name—Iron Castle—derives from its legendary impregnability, attributed to double walls, inaccessible gates, two cisterns, and sheer rock slopes. Medieval legend tells of the King of Castile's ingenious siege strategy involving fire-lit goats to overcome its defenses. Though partially ruined today, the restored remnants still command the landscape and remain a monument of significant cultural interest, representing the resilience of late Moorish strongholds in Andalusia.
