Campagna di Roma (kämpä`nyä dē rô`mä), low-lying region surrounding the city of Rome, c.800 sq mi (2,070 sq km), Campania, central Italy. A favorite residential area in Roman times, it was later largely abandoned for centuries because of the prevalence of malaria and the lack of sufficient water for cultivation. Much of the region was reclaimed in the 19th and 20th cent. It is now used to grow crops and to pasture cattle; new settlements have been founded. There are remains of Roman aqueducts and tombs.
