South of Giulio Agricola metro stop stretches one of Rome's best kept secrets – il Parco degli acquedotti –– as majestic in its way as the Colosseum but hardly a tourist in sight and not associated with mass bloodshed.
There across Rome's campagna the Aqua Claudia is still striding strong, in places two arches high. No wonder Frontinus, curator aquarum, dubbed it magnificentissimus. All the more so when measured against the Acqua Felice (after the 16th-century Pope Pius V, otherwise known as Felice Peretti) which runs parallel to it, a chunk of Acqua Marcia tacked on to the end.
