Fortaleza de la Mota in Alcalá la Real represents one of the largest walled perimeters in Andalusia, perched at 1,029 metres elevation in Jaén province. Built primarily in the 13th and 14th centuries as a Nasrid fortification, it was transformed into a major Christian frontier stronghold after 1340 when Alfonso XI's siege forced capitulation. The fortress preserves its original Almohad walls, Renaissance urban layout, and the distinctive frontier landscape shaped by medieval Christian and Muslim occupation. Declared a Bien de Interés Cultural in 1993, the site marks where the Kingdom of Castile once confronted the Nasrid Kingdom of Granada.
