The most famous pair of towers are located at the intersection of the roads that lead to the five gates of the old ring wall (mura dei torresotti). This was the site of the early medieval Gate to the Via Emilia, the Porta Ravennate, now remembered by the name of the adjacent Piazza di Porta Ravegnana. The taller tower is called the Asinelli while the smaller but more leaning tower is called the Garisenda.
