Athens are about ruins and archeological sites. So if you are expecting something else don't visit. I found this structure very impressive but I looked at it as a part of history of the world. It was something more in the past. It was worth visiting to take some good pictures. If you stand in one of the corners you can get this temple, acropolis and the Arch of Hadrian in one picture. I paid €12 for joined ticked and this ticket covered some of the archeological sites in Athens (including Acropolis).
