The centerpiece of the artificial lake in Parc de la Ciutadella is the Font de la Cascada. The elaborate, two-tiered waterfall is fronted by four dragon sculptures. Inside of the arch is a statue by Venanci Vallmitjana of Venus on a clam shell. This imagery is a tribute to “The Birth of Venus” painted by Sandro Botticelli in 1480. The fountain was designed by Josep Fontsére with the help of a young student named Antoni Gaudí. Gaudí would become Barcelona’s most famous architect.
