Monti is a wedge of steep lanes between the Forum and the main railway station, and it is the quarter in central Rome where people still live and work at street level. In antiquity this slope was the Suburra, the crowded, cheap, noisy district packed below the palaces on the hill; its name was an insult in Roman writing, and Julius Caesar grew up there. The medieval quarter that replaced it kept the shape: narrow lanes running downhill, joined by stairs, with workshops on the ground floors.
It is Rione I, the first of Rome's fourteen historic districts by number, and Romans still give addresses by rione rather than by postcode. Via Cavour was driven through the middle of it in the 1880s and cut the quarter in two, which is why the two halves feel different. The centre of daily life is Piazza della Madonna dei Monti, where a sixteenth-century fountain stands in the middle of a small sloping square. From early evening people sit on its steps with a glass, and the square fills with a noise the residents in the flats above have been complaining about for years.
