The birthplace of Christopher Columbus, Genoa has always played a big role in Italian maritime trade and is still one of the largest ports in Italy. Though Genoa is often overlooked as a tourist destination, it is a wonderful Italian city, and definitely worth visiting. The aquarium in Genoa is the largest in Europe, and it is perhaps the most popular tourist attraction in the city. If you gravitate more towards art and architecture, then the art galleries found at the Prince’s Palace and in the Raccolte Frugone are well worth a visit. Foodies love Genoa, and it is easy to see why. Pesto originated from Genoa, and the affordable flat-bread called focaccia is also delicious and readily available throughout the city.
