Alcázar de la Puerta de Sevilla in Carmona represents an extraordinary palimpsest of Iberian, Phoenician, Carthaginian, Roman, Moorish, and Christian occupation spanning from the 14th century BC onward. This Moorish fortress, commanding the western flank of Carmona's defensive system, underwent major alterations in the 14th and 15th centuries. Visitors explore the cistern yard, Prisoners' Hall, and Tribute Tower, or ascend the Golden Tower for panoramic views. The Alcázar became a UNESCO-recognized historical landmark even before Seville's Giralda received similar recognition. Now serving as Carmona's Tourist Reception Centre, it encapsulates the cultural layering of medieval Andalusia.
