Castillo de Granadilla preserves a remarkable medieval fortress within the abandoned but beautifully maintained village of Granadilla in northwestern Cáceres province, Extremadura. The castle's origins trace to the 9th century when Muslim settlers constructed an alcazaba, later conquered by Ferdinand II of León in 1160 and subsequently modified by Christians who added fortified town walls. The current fortress, commissioned by Don García Álvarez de Toledo, the first Duke of Alba, in the 15th century, showcases Italian architectural influence through its distinctive design featuring a central tower surrounded by four semicircular towers with polylobular floor plans across four stories. Though originally designated a flood zone when the Gabriel y Galán reservoir was constructed, the village and castle remarkably remain dry and well-preserved, having earned designation as a Historical-Artistic Site in 1980 and selection for inclusion in Spain's Program for the Recovery of Abandoned Towns.
