The two leaning towers, the Torre Asinelli and the Torre Garisenda, dating from 1109 and 1110 respectively, are among the most remarkable structures in Bologna: they are square brick towers, the former being 320 ft. in height and 4 ft. out of the perpendicular, the latter (unfinished) 163 ft. high and 10 ft. out of the perpendicular. The town contains many fine private palaces, dating from the 13th century onwards. The streets are as a rule arcaded, and this characteristic has been preserved in modern additions, which have on the whole been made with considerable taste, as have also the numerous restorations of medieval buildings. A fine view may be had from the Madonna di S. Luca, on the south-west of the town (938 ft.). Among the specialities of Bologna may be noted the _salami_ or _mortadella_ (Bologna sausage), _tortellini_ (a kind of macaroni) and liqueurs. Bologna is an important railway centre, just as the ancient Bononia was a meeting-point of important roads. Here the main line from Milan divides, one portion going on parallel to the line of the ancient Via Aemilia (which it has followed from Piacenza downwards) to Rimini, Ancona and Brindisi, and the other through the Apennines to Florence and thence to Rome. Another line runs to Ferrara and Padua, another (eventually to be prolonged to Verona) to S. Felice sul Panaro, and a third to Budrio and Portomaggiore (a station on the line from Ferrara to Ravenna). Steam tramways run to Vignola, Pieve di Cento and Malalbergo.
