'Monti' means 'The Hills,' and the device of the Region represents three, figuring those enclosed within the boundaries of this district; namely, the Quirinal, the Esquiline and the Coelian. The line encircling them includes the most hilly part of the mediæval city; beginning at the Porta Salaria, it runs through the new quarter, formerly Villa Ludovisi, to the Piazza Barberini, thence by the Tritone to the Corso, by the Via Marforio, skirting the eastern side of the Capitoline Hill and the eastern side of the Roman Forum to the Colosseum, which it does not include; on almost to the Lateran, back again, so as to include the Basilica, by San Stefano Rotondo, and out by the Navicella to the now closed Porta Metronia. The remainder of the circuit is completed by the Aurelian wall, which is the present wall of the city, though the modern Electoral Wards extend in some places beyond it. The modern gates included in this portion are the Porta Salaria, the Porta Pia, the new gate at the end of the Via Montebello, the next, an unnamed opening through which passes the Viale Castro Pretorio, then the Porta Tiburtina, the Porta San Lorenzo, the exit of the railway, Porta Maggiore, and lastly the Porta San Giovanni. The Region of the Hills takes in by far the largest area of the fourteen districts, but also that portion which in later times has been the least thickly populated, the wildest districts of mediæval and recent Rome, great open spaces now partially covered by new though hardly inhabited buildings, but which were very lately either fallow land or ploughed fields, or cultivated vineyards, out of which huge masses of ruins rose here and there in brown outline against the distant mountains, in the midst of which towered the enormous basilicas of Santa Maria Maggiore and Saint John Lateran, the half-utilized, half-consecrated remains of the Baths of Diocletian, the Baths of Titus, and over against the latter, just beyond the southwestern boundary, the gloomy Colosseum, and on the west the tall square tower of the Capitol with its deep-toned bell, the 'Patarina,' which at last was sounded only when the Pope was dead, and when Carnival was over on Shrove Tuesday night.
