9. Cape Sounion
If the Greek god of the sea, Poseidon, were alive today, Cape Sounion would be the location of his temple. Indeed, the ruins are still there, to this day, perched on the southernmost tip of the Attica peninsula. Surrounded by the sea from three sides, the temple once stood on the headland, as if it called to its master to come home.
Today, however, it is rightfully among the top tourist attractions in Greece, as evidenced by thousands of tourists that visit it mostly thanks to day-excursions from Athens and other locations. Viewed from the ruins, the sunset over the Aegean Sea is a well-known event enjoyed by many on a daily basis.
