Probably the best museum in the world for marble sculpture
Patission avenue, Athens
Elefsina is ancient Eleusis, home of the so-called the Eleusinian mysteries in honour of Demeter. It is about 25 km (15 miles) into the sprawling suburbs of the city. But you are getting away from the tourists and, if you have some imagination, it makes a memorable change to the crowd-packed Acropolis.
As I said it's about 25 km heading west(ish). It's easy to get there in your own car but there is also plenty of public transport
