Piraeus, Port of Athens
Piraeus has been a major Greek city since the Golden Age of Greece. The city was planned by Hippodamus, an acomplished architect. Further development took place during the times of the Persian War, when Piraeus was integral to the defence of Athens, as the linking corridor between the city and port was strengthened by stone walls. Later, during the Renaissance era, Piraeus was named 'Porto Leone', due to the beautiful marble lion standing over the harbor. Unfortunately, the lion was stolen and moved to Venice, where it still stands. Nowadays Piraeus is the biggest harbor in Greece, and one of most important in the Mediterranean Sea. Cruises from Piraeus leave for a multitude of destinations in the Greek Islands and beyond. It's 10km from Piraeus to Athens, and by train the journey time is around 45 minutes.
