The Parioli district, a quiet and residential area set up and developed between the end of the 19th century and the 30s, has a history that dates back to the Middle Ages, to the period when it was called Pelaiolo. After World War II, the district reached the peak of notoriety; as a matter of fact, it hosted people from the cinema, theater, industry, high finance and diplomacy. In the sixties, taking an aperitif at the local bar had become a must. The houses of this district always feature reserved yet extensive green spaces, with beautiful gardens, and now this neighborhood, a stone's throw from the centre, is one of the greenest one in Rome.
