The streets of Bologna as seen from the Torre degli Asinelli, Bologna, Italy.The Two Towers, both of them leaning, are the symbol of Bologna. They are located at the intersection of the roads that lead to the five gates of the old ring wall (mura dei torresotti). The taller one is called the Asinelli while the smaller but more leaning tower is called the Garisenda. Their names derive from the families which are traditionally credited for their construction between 1109 and 1119.
