Castillo de Tíscar, also known as Peñas Negras Castle, occupies a dramatic rocky ridge approximately 13 kilometers south of Quesada in Jaén province. The fortress dates to at least the 9th century, with records mentioning Cordoban military campaigns against it in 896. Positioned on the formidable Peñas Negras rock formation, it commanded views over the Sanctuary of Tíscar and surrounding valleys. The small enclosure features a tower of homage built from rammed earth and masonry, with Christian constructions from the 14th century overlaying earlier Andalusian remains. Now in ruins and freely accessible, the site reflects centuries of Christian-Muslim control and strategic importance in medieval Andalusian defense.
