The Parco degli Acquedotti covers an area of about 240 hectares in the south east of Rome. Its name derives from the ruins of six of Rome’s 11 aqueducts: Anio Vetus, Aqua Marcia, Aqua Tepula, Aqua Iulia, Aqua Claudia and Anio Novus. In addition, there is the Acqua Felice aqueduct, built during the Renaissance, and still used for irrigation. Other interesting ancient buildings in the area include: villa delle Vignacce, casale di Roma Vecchia, which gave its name to the entire area, and villa dei Sette Bassi.
Today large part of the conduits are no longer visible, partly because many had an underground route and also because the external structures of the oldest aqueducts were occupied over time by more recent constructions. E.g., parts of the Aqua Tepula aqueduct were incorporated into the Aqueduct Felix as were those of the Aqua Marcia. The Claudia and Anio Novus aqueducts are also architecturally important: as they traverse the park they encapsulate each other and overlap in the same arched structure. 155 columns support the arches, almost 28m high, before crossing paths with the Aqua Marcia aqueduct before heading towards the Appia Antica where they meet again at the height of Tor Fiscale.
