It’s the last fountain committed by a pope to show the waters of a restored aqueduct. The aqueduct is the Acqua Pia Antica Marcia built between 1865 and 1870 by the will of Pope Pius IX. It is therefore the last papal fountain and the first of Rome, capital of Italy. When the fountain was finished the scaffolds were kept as it seemed too sensual, with all that nymphs playing with sea animals. Yet the romans saw the fountains through the scaffolds and took those away. We still like it a lot. In front of the fountain is the splendid church of Santa Maria degli Angeli and the extraordinary museum of palazzo Massimo.
