The port city of Genoa has a rich history of many centuries. It is the sixth largest city in Italy, with Europe's largest old town. Via Garibaldi (formerly Strada Nuova) is known for many baroque palaces. In addition, the city is famous for its "karudzhi" (narrow streets). On the main square of the Ferrari is the Palazzo Ducale and Carlo Felice Theatre; not far from where Christopher Columbus was born. Tourists should visit the largest aquarium in Europe, Genoa.
