A mythical source
Although it's officially called Fuente de la Princesa (princess' fountain), this is known throughout the city as Neptune's Fountain. It dates back to 1845, and although it has stood at various locations, it was moved to this park in 1902. Until that date, it was a functional fountain, supplying water to the city of Zaragoza, but now it is purely decorative. It has an image of the god Neptune and four dolphins.
