Charles V had a huge architectural impact on Alhambra during his reign as king of Spain and Holy Roman Emperor. The first evidence you will encounter is the Fountain of Carlos V, also called Pilar de Carlos V. Below a relief of his heraldic shield are two pomegranates. They are flanked by three heads spouting water. These allegories represent Granada’s rivers Genil, Darro and Beiro. On the wall are four medallions portraying mythological events of Hercules, Daphne, Alexander the Great and the sisters Frixo and Hele. Charles V Fountain was finished in 1545.
