La Torre del Oro, or the Golden Tower, is one of the last buildings remaining from the arab times in Spain, around 1300 years ago, give or take a hundred years. It is said that was covered in gold, therefore the name, but as history has taught us, these things hardly make it to our times intact. Still is an outstanding monument, worth a visit. It is also said that this tower was part of the protective walls of the once so called Hispalis.
