The City at Sea - Genoa, Italy
Genoa grew from the fishing settlements on the coast of sea and in the course of time extended along the sea by 35 kilometers, since it is not possible to grow landwards because of Apennine mountains.
Therefore, the main sight of Genoa is, to my mind, everything which is connected to the sea: old port (Porto Antico), Aquarium, etc. And although the old city of Genoa is also not less interesting, we spent the most time of the day in the port. It is difficult to see everything in one day.
Columbus's year, famous architect Renzo Piano considerably changed the appearance of old port haven opened it to the city and built new constructions, including panoramic elevator and aquarium.
Since then the port became the favourite promenade place of townspeople and numerous tourists.
