Many people make the trip along the Apollo Coast to Cape Sounion to see the Temple of Poseidon. It has stood on this hilltop, overlooking the the Aegean since the 5th century B.C. and was built to honour Poseidon, God of the sea and brother to Zeus. Although only parts of the Temple now remain, the setting is so dramatic that you can imagine people becoming members of Poseidon's cult, just so they could worship here. It was built using Doric columns, the most simple of the three Greek architectural styles and it is the simplicity that so intrigued me. No fancy do-dads, just clean simple lines of white marble against the blue sky and the blue sea below - breathtaking!
If you have your own transporation, getting here is a cinch. Otherwise, city buses run from downtown Athens and take about 1 1/2 hours. You can also join a bus tour to Sounion, some of which include lunch or dinner at one of the nearby beach tavernas.
It can be pretty crowded unless you get here in the early morning before the tour buses arrive. We took a break from the crowds and wandered down to the beach to relax for awhile. When it got too hot, we stopped for a snack in a shady spot at one of the tavernas.
At night it can be cool, especially with the breeze from the Agean so you might want to bring a jacket.
The best time to see the Temple is at sunset when the Agean takes on a fiery, red glow that makes you wonder if Posiedon isn't still around, keeping watch on his temple.
