Many people think that the oldest temple of Greece is the temple of Athena in Acropolis. Yet, the Temple of Poseidon in Sounio is the first reported by Homer. Specifically, Homer reports that Menelaus’ Ship Captain named “Fronti” during their return from Troy, died at the sight of Sounio Sanctuary. Meneleaos stopped and buried his Captain in the Holy Ground of Sounio.
Yet, Sounio is reported as a place even earlier than Trojan War, and specifically in the Myth of Theseus and Minotaur.
THE MYTH
The myth is chronologically placed a millennium before the temple of Poseidon was built.
Around 1,450 BC Athens was a kingdom, at that time, and it had to pay a regular tax and a blood tax to Minoan Crete. The blood tax was paid every nine years, and seven young men as well as seven young women were sent to Crete to be fed to the Minotaur. Minotaur was a creature with a bull's head, tail, and a male body, while he was living in the Labyrinth.
