The beaches of Castile, a must in trade with North America and Europe, were visited and plundered by pirates coming from the North African coast. For this reason, in the late sixteenth century and along the coast, built a series of towers called Torre Almenara. The mission of these towers was to provide shelter and watch the coast of Huelva. Today along the beaches can contemplate many towers of this type, such as the San Jacinto is, Zalabar, Carbonera, the Asperillo, Parrot and perhaps most emblematic of all Matalascañas, the de la Higuera, which is reflected in the passage of time by not more than the base is destroyed and overturned by the action of the ocean. This one is the Torre del Loro in Mazagón near Doñana Natural Park.
