ATHENS METRO: inaugurated in 2001, during the preparations for 2004 Olympic Games. The works not only brought to light some evidence from the Classical Greece, but also the one belonging to a neolithic Athens, very important for understanding the city’s development. Athens nowadays has one of the beautiest and most functional metro systems of Europe, a true jewel of the city. Lots of the metro stations are true museums, no-charge visitable (under the Acropolis there are 5 metro stations: Syntagma, Montastiraky, Thissio, Akropoli, Panepistimio). Besides, Athens Metro sees in these the possibility of assisting to several art galleries, where important works of contemporary Greek artists are located (Giorgios Zoggolopoulos, Yannis Moralis and Chryssa). An authentic museum where modern and ancient share a wonderful fascinating surrounding.
