I took this picture of the Parthenon 10 years ago on a visit to Athens. Socrates’ school was on the opposite side at the bottom of the hill in the Agora.

Halfway up the hill (towards the Erechthion - the small temple in back) from his school are the caves of Apollo and Pan (you can still visit both). Just imagine Socrates taking the students up there and inspiring Plato to write a certain allegory.
