Dog Point), a projection of land into the Atlantic Ocean in the city of Chipiona, about 6 kilometres (3.7 mi) southwest of the Guadalquivir entrance, and serves as the landfall light for Seville.

It was ordered to be built in 140 BC by the Roman proconsul Quintus Servilius Caepio in an attempt to finally overcome the problems of the Salmedina reef at the mouth of the then river Betis, now the Guadalquivir.

The project to build a modern lighthouse on the site was first developed in 1862 by Jaime Font, a Catalan engineer.

The first when it was switched off was in 1898, during the war against the United States of America over the independence of Cuba, all the lighthouses around Cadiz were turned off because an invasion was feared.

It is built of blocks of sandstone and oysterstone, a limestone sedimentary rock that is open in structure and with visible remains of mollusc shells, especially of the oyster family.
