The Province of Cádiz is in south Spain. Its capital is Cádiz, an ancient port city on a promontory. It’s home to a gold-domed cathedral and more than 100 watchtowers, like the Torre Tavira. North, Doñana National Park is a major wetland bird habitat. Jerez de la Frontera is known for its Moorish fort, sherry and equestrian school. Bodegas dot the sherry towns of Sanlúcar de Barrameda and El Puerto de Santa MarÃa.
