It's probably one of the most beautiful subways I've seen!! There's still many sculptures and excavations today, it's so nice to see a part of history in everyday life. If you're not using the subway to get around, you should at least check it out for the artifacts.We spent so much time going around the stations! In 2004, we spent 3 days in Athens. The metro was fairly new. In most stations, there was a display of the excavation and building. Remember, Athens is OLD!! Dig a hole and find a temple, was the phrase used during the time of getting ready for the Olympics.
So, don't rush! Have fun and go to Monistiraki flea market on Sunday!
