Located at the mouth of the Guadalquivir river (which crosses Seville) and the Atlantic Ocean, Sanlucar is known for the famous horse-race on its beach. The city is also home to the Orleans and Bourbons Palace, which boasts a Neo-Mudéjar style and bow windows. Built in the 19th century, it is a copy of the mosque of Cordoue! It is pleasant to stroll around its cobblestone streets and discover the beautiful façades enhanced with gardens and orange trees, churches and convents, markets, castles and squares. Sanlucar is divided into a lower town and an upper town. It is also the home of Manzanilla Sherry and has many cellars that can be visited. Finally, Christopher Columbus left from Sanlucar for his third voyage in 1498. However, he wasn't the only important explorer to sail from this port: in 1519 Magellan set off for his famous first world tour from which he never returned as he was killed in the Philippines. A plaque pays tribute to the 18 sailors (out of the 165 who departed) who returned in 1522, completing the first circumnavigation of the world in history!
