Temple of Apollo
Corinth is an especially interesting place to visit. You have the ancient Greek history, it is where Oedipus was raised before he famously played his father and married his mother. Agamemnon lead many Corinthians in the Trojan War, and and Jason (As in the Argonauts) spent time there.
And slightly more recently (relatively speaking),
Paul preached to the Corinthians, and his later letters to the Corinthians because 2 books of the Bible, so the history spans a huge period of time.
Corinth Archaeological site
The ancient city is not a huge site but it is extremely well signposted and once of the most interesting sites I have visited. You can easily spend a few hours wondering around the site.
Corinth Archaeological Site
This temple is the first of the many ancient Greek ruins I have visited. It is one of the many temples dedicated to Apollo in Greece. There is not much left of the temple; only a single standing column is remaining. The temple is a short walk from Aegina Town, and it has a lovely little museum attached to the site. It was a peaceful temple to visit; there were only 2 other people visiting it; so you have plenty of time to wonder around the site in piece, and chat to the friendly staff working in the museum.
A very different experience from the noisy and crowed (yet magnificent) Acropolis.
