Piraeus is the main port of Athens and the most significant in Greece and the Eastern Mediterranean. It is a starting point for ships to most islands of Greece and an important destination for many cruise ships.
Since ancient times the Athenians gave great importance to the port of Piraeus, which was the base of their naval forces. They had catered greatly to fortify it with walls, parts of which still stand today.
Piraeus port also had other names, including the famous "Porto Leone", owing to the marble lion that used to be at the port's entrance. Today in this very spot you will find a duplicate, since the original was stolen by Morosini and moved to Venice.
Once in Piraeus, during the day you can visit the Archaeological Museum of Piraeus and the Maritime Museum, stroll around the docks and the port or simply gaze at the vessels. If you get hungry, there are a lot of restaurants and taverns with fresh fish, seafood or anything else you may desire. Otherwise, if you are not hungry (or right after you eat) you can have your coffee in one of the several cafes by the sea and enjoy the spectacular view.
All that during the day, because once night falls, Piraeus becomes the center of entertainment. With Mikrolimano as focal point, fantastic clubs by the sea and great bars give you a sense of Greek nightlife.
