Temple of Poseidon, Sounion

Listen first. Below you, far down the cliff, the sea moves against the rocks. Up here the wind comes off the water, warm and salty, and it pushes at your clothes. Under your feet the ground is pale and dusty, broken by scrub and grey stone. Ahead of you, a row of white columns stands against an open sky. There is nothing behind them but the sea. That emptiness is part of the design.

You are standing at Cape Sounion, the southern tip of Attica. Attica is the region around Athens. This is the last point of the mainland before the open Aegean Sea. For sailors in the ancient world, this headland mattered. Ships coming home to Athens passed here. Ships leaving Athens saw this cape as the last piece of home. So the Athenians placed a temple to Poseidon, god of the sea, exactly where every sailor could see it.

The temple in front of you dates to the mid fifth century before Christ, most often placed around the 440s. That is the same generation that built the Parthenon in Athens. But it was not the first temple on this spot. An earlier temple stood here, and it was never finished. The Persian army destroyed it during their invasion of Greece in 480 BCE. The Athenians later rebuilt, and what you see now is that second temple.

The style is Doric. Doric is the plainest of the classical Greek orders. The columns have no base, and the tops are simple cushions of stone rather than scrolls or leaves. The temple was built with a single ring of columns around a central room. That room once held a statue of the god. Today the room is gone, and only part of the outer ring survives. Roughly fifteen columns still stand, and they give the site its outline against the sky.

Here is a detail most visitors miss. Look closely at the vertical grooves cut into each column. These grooves are called flutes. Most Doric columns of this period carry twenty flutes. These columns carry only sixteen. Scholars have offered different explanations. Fewer, wider grooves may resist the salt wind better. They may also make the columns look slimmer and taller from a distance. Either way, the builders made a deliberate choice here.

The stone itself is local. It is a white marble from quarries in the nearby hills, not the famous marble of Mount Penteli used for the Parthenon. Run your eyes along the surface. You will see grey veins, small pits, and patches where the wind and salt have worn the marble soft. Some scholars think the same unnamed architect designed this temple and the Temple of Hephaestus in the Athens Agora. The proportions are close. But no ancient source gives us his name.

Now turn toward the sea and think of the oldest story told about this cliff. Legend has it that Aegeus, king of Athens, waited here for his son Theseus. Theseus had sailed to Crete to fight the Minotaur, the half-man, half-bull monster. The two agreed on a signal. White sails would mean Theseus was alive. Black sails would mean he was dead. Theseus won, but he forgot to change the sails.

According to the tale, Aegeus saw the black sails from this headland. He believed his son was dead, and he threw himself into the water below. The sea, the story says, took his name. It became the Aegean. This is myth, not history. But it shows how long people have connected this cape with watching, waiting, and loss at sea. Even Homer, in the Odyssey, calls Sounion a sacred cape.

The site was more than a religious place. It was also a military post. During the long war between Athens and Sparta in the late fifth century before Christ, the Athenians fortified this headland. They wanted to protect the ships carrying grain to the city. You can still trace parts of the old walls on the slopes. Look for low lines of rough stone, very different from the smooth marble of the temple.

The land around you held another kind of wealth. The hills of this district, near the modern town of Lavrio, contained silver. The ancient mines here were worked for centuries, often by enslaved people in harsh conditions. In the early fifth century before Christ, a rich new seam was found. Athens used that silver to build a large fleet of warships. That fleet helped defeat the Persians at sea. So the temple and the mines are part of one story.

Now for a smaller, more modern detail. Walk slowly around the columns and look for names cut into the marble. Travellers of the eighteenth and nineteenth centuries often scratched their names into ancient stone. One name here is said to be that of Lord Byron, the English poet. Byron did visit Sounion, and he wrote about its marble cliff in his poetry. Whether he cut the letters himself, nobody can prove. The column is now protected, so please look but do not touch.

It also helps to know what is not here. Large marble statues of young men, called kouroi, were found at this sanctuary. They are much older than the temple, from the sixth century before Christ. They now stand in the National Archaeological Museum in Athens. On a lower hill nearby, there are also the remains of a smaller sanctuary to Athena. Many visitors walk past it without noticing.

If you can, stay until the light changes. In the late afternoon, the sun drops toward the sea to the west. The marble turns from white to warm gold, then to pink. The shadows of the columns stretch across the ground. This is when the site is busiest, but it is also when the temple looks the way most people remember it.

Before you leave, stand still for a moment and look out past the columns. Count the islands on the horizon. Watch a ship move slowly across the water. For two and a half thousand years, sailors looked up from that same water and saw this white shape on the cliff. Now you are the one looking down. As you walk back along the path, listen again to the wind and the sea below.
