The Cathedral de Sevilla, also known as Cathedral de Santa María de la Sede, is a Roman Catholic cathedral in Seville, Spain. After its completion in the early 16th century, the Cathedral supplanted Hagia Sophia as the largest cathedral in the world, a title the Byzantine church had held for nearly a thousand years. It was registered in 1987 by UNESCO as a World Heritage Site, along with the Alcázar and the General Archive of the Indies. The Cathedral is also famous as the burial site of Christopher Columbus.
The Giralda bell tower, like many other bell towers in Andalucia, is the former minaret of the mosque that stood on the site under Muslim rule, and was built to resemble the minaret of the Koutoubia Mosque in Marrakech, Morocco. It was converted into a bell tower for the cathedral after the Reconquista, although the topmost section dates from the Renaissance. The tower is 343 ft in height and was one of the most important symbols in the medieval city. It remains one of the city’s most iconic symbols today.
