Oh, the metros I have known on this trip...going into the Athens metro I didn't know what to expect beyond stories I remember hearing about the troubles of traveling around Athens during the 2004 Summer Olympics. ...but should you really judge a metro at a time when you have more tourists than possibly ever before.
Although parts of the metro system date back to the 1860's most of the underground lines were built in the 1990's. This recent construction has allowed it to be one of the cleanest and most efficient subways in the world. Plus, your metro doesn't have these ruined sculptures waiting for you.
Here's a view of the opposite track with some more classical Greek sculptures.
