Aphaea was a local goddess and this was her only shrine. She was worshiped from the 14th century BC but by the 2nd C BC she'd merged into Athena and Artemis. This temple, built 500 BC, was on the site of an earlier temple that burned down. It's a fine Doric shell on a ridge of pine trees, depicted by JMW Turner among others. Most of its sculptures are now in the Glyptothek in Munich.
The Temple of Aphaia is an Ancient Greek temple located within a sanctuary complex dedicated to the goddess Aphaia on the island of Aegina, which lies in the Saronic Gulf. Formerly known as the Temple of Jupiter Panhellenius, the Doric temple is now recognized as having been dedicated to the mother-goddess Aphaia. It was a favourite of Neoclassical and Romantic artists such as J. M. W. Turner. It stands on a c. 160 m peak on the eastern side of the island approximately 13 km east by road from the main port.

Small museum and remains of a citadel on Kolona headland, you mostly come for the view. "Kolona" refers to the column, still standing, which was a daymark for approaching ships.
Kapralos (1909-1993) was a Greek artist who often spent summer working here on Aegina; his best known piece is the 40 m Pindus Frieze. You'll know you've reached the museum by the statue of his mother outside. It's nowadays an annexe of the National Art Gallery (Alexandros Soutzos Museum) in Athens.
