Castillo de Castell de Ferro is a medieval fortress perched on the coast near Gualchos in Granada's Costa Tropical. Built during the Nasrid era, this fortified castle served as a vital defensive stronghold against Barbary pirate raids and controlled access to the Alpujarras region. Strategically positioned on a clifftop between rocky coves, the castle features a quadrangular design with associated watchtowers including the Estancia and Cambriles towers, creating a comprehensive surveillance network along the shoreline. The ruins retain evidence of its military architecture and continue to command panoramic views of the Mediterranean coast, offering insights into medieval Andalusian defensive systems.
