I was reading a blog posting where the author suggested that while the Acropolis is a place worth seeing there is not a lot else in Athens and recommended going to Mykonos or Santorini instead.
Well I have to disagree with that because Athens is a wonderful city for visiting ancient monuments and buildings, in addition to the Acropolis there is the Ancient Greek and Roman Agora and the dramatic Temple of Zeus with its spectacular columns thrusting triumphantly into the sky.
