The Temple of Aphaia in Aegina was built later on the hill rising above Agia Marina. The goddess Aphaia (meaning "invisible") was only worshiped in Aegina and the practice had begun in prehistory. The temple, however, became an important, symbolic centre of Greece.
The Monastery of Agios Nektarios
The monastery and the new cathedral of Agios Nektarios are places of worship, comfort and spiritual renewal for thousands of Greeks and foreigners who visit throughout the year. Those visiting the monastery may pay their respects to the saint's relics and visit the room where he lived and wrote, away from the everyday world. The monastery observes the date of the saint's death on 9 November, and on 3 September observes the transfer of his remains.
The Temple of Apollo at Kolona
Excavations at the top of Kolona hill uncovered the foundations of the Temple of Apollo (520-500 BC). It was a peripteral temple of the Doric order, with 12 columns along the longer sides and six on each of the shorter sides. Only one Doric column about 8 m tall remains; this was part of the temple's opisthodomos (rear section). In 1975, Chandler refers to there being two erect columns, one of which also retained the capital and architrave at the top.
Paleochora the Old Town of Aegina
Paleochora, or "old town", is the name of a hill near the Monastery of Agia Triada (Agios Nektatios) dotted by a scattering of old chapels and remains of a Byzantine city. It is also known as an "island Mystras," alluding to the fortified town in the Peloponnese.
Aegina is an island with a mythical tradition and a history that begins from the Neolithic times. The many ancient sites that exist in the surrounded regions enrich its heritage parts of which can be seen today at the several museums. Of high interest is the Archaeological Museum of Aegina, Aphaia museum, Folklore and Historical museum,Christos Kapralos Museum
