Castillo del Cachorro near Torreorgaz in Cáceres, Extremadura, comprises a medieval stone tower and fortified house remains set north of the Salor River. The fortress features a 13th-century tower of Muslim origin and was later acquired by the Ulloa family, who established the Lordship of Torreorgaz in the late 15th century. The keep, constructed from large squared stone blocks, bears the Ulloa family crest, while the castle's distinctive name derives from Don Gonzalo Ulloa y Carvajal, the fourth lord, known as "el Cachorro." This structure exemplifies the architectural blend of Moorish and Gothic influences characteristic of medieval frontier fortifications.
