Temple of Apollo Patroos in Municipality of Athens

You're standing on the west side of the Ancient Agora of Athens, next to some low foundations in the ground. It may not look like much, but this is where the Temple of Apollo Patroos stood. Look up at the hill behind it. That's the Temple of Hephaestus, still almost completely intact. Right to the north of these remains stood the Stoa of Zeus. With those two as landmarks, you can rebuild the old marketplace in your mind.
