The Athens Metro keeps getting better and better with age; not only new routes and new stations but also new exhibitions of archaeology and art.
We seldom go to Athens without visiting the Monastiraki area. Now we can also tour an ancient river bed in the Metro station. Many writers in Athen's golden age referred to the Eridanos River but the Roman Emperor Hadrian had it covered over as a public improvement in the 2nd century A.D.. Now an excavated portion of the stream bed and banks may be observed in the station and supposedly if it is quiet enough you can still hear the running water.
Many of the other stations also display what was excavated during their construction, including the main Syntagma Square station. Don't miss it.
