One of the great glories of ancient Greek art, the Temple of Aphaia is among the most extant examples of classical Doric architecture. Once adorned with an exquisite group of pedimental sculptures (now in the Munich Glyptothek) it still proudly bears 25 of its original 32 columns, which were either left standing or have been reconstructed. The structure is perched on a pine-clad promontory, offering superb views of Athens and Piraeus across the water—with binoculars
you can see both the Parthenon and the Temple of Poseidon at Sounion. The saying goes that the Ancient Greeks built the Temple of Aphaia in Aegina, the Parthenon in Athens, and the Temple of Poseidon at Sounion as the tips of a perfect equidistant triangle (called Antiquity's Perfect Triangle). This site has been occupied by many sanctuaries to Aphaia; the ruins visible today are those of the temple built in the early 5th century BC. Aphaia was apparently a pre-Hellenic deity, whose worship eventually converged with that of Athena.
You can visit the museum for no extra fee. The exhibit has a reconstructed section of the pediment of the temple, many fragments from the once brilliantly colored temple interior and the votive tablet (560 BC) on which is written that the temple is dedicated to the goddess Aphaia. From Aegina town, catch the KTEL bus for Ayia Marina on Ethneyersias Square, the main Aegina town bus station; ask the driver to let you off at the temple. A gift and snack bar across the road is a comfortable place to have a drink and wait for the return bus to Aegina town or for the bus bound for Ayia Marina and its pebbled beach.
