Cape of Sounion, with its famous temple dedicated to the god Poseidon, is one of the most beautiful natural areas of Attica and one of the most impressive archaeological sites in Greece. In ancient times it was called Sounias Akra (edge) and was connected with the legends of Athens and the Aegean. Cape Sounion is the spot where Aegeus, king of Athens, allegedly jumped off the cliff, thus giving his name to the Aegean Sea. It is also referred to as a sacred place in the Homeric epics. The site was chosen for its direct relationship with the sea since this was the last piece of land seen by ships departing from Athens and the first on returning from their voyage.
The site of Sounion has been inhabited since prehistoric times. From the 8th century BC, however, the cult of Poseidon and Athena started to develop, but the sanctuaries were destroyed in 480 BC by Persian troops during Xerxes I’s invasion of Greece. In the mid-5th century BC, by order of Pericles, the Temple of Poseidon was rebuilt, the ruins of which now dominate the cape’s summit with its 16 standing columns partly restored.
In a maritime country like Greece, the god of the sea was bound to occupy a high position in the divine hierarchy. All mariners greatly feared his implacable wrath, manifested in the form of storms. In an age without mechanical power, storms frequently resulted in shipwrecks and drownings. Therefore, the sanctuary of Poseidon was a venue where mariners, and entire cities or states, could propitiate Poseidon by making animal sacrifices or leaving gifts.
Poseidon’s sacred precinct (temenos) was entered through a monumental gateway of poros and marble to the north of the temple, the propylaea. Beyond, along the north side of the temenos, runs a stoa, some 40 m. long by 9 m. wide, divided into two aisles by an internal colonnade of six columns. A second smaller stoa occupied the west side of the precinct. The stoas served as accommodation for visitors to the sanctuary.
The temple of Poseidon is a Doric peripteral temple with six columns on the narrow sides and thirteen on the long ones, made of locally quarried white marble. At the centre of the temple, the colonnade would have been the hall of worship (naos), a windowless rectangular room similar to the partly intact hall at the Temple of Hephaistos in Athens (considered to be the work of the same architect). It would have housed a colossal bronze statue of Poseidon.
A sculptured frieze originally lined the four sides of the area in front of the pronaos. It depicted the Battle of the Centaurs, the Battle of the Gods and Giants, and the deeds of Theseus. However, like on the temple of Hephaistos in Athens, there was no frieze decoration on the metopes. The relief friezes have suffered considerably from climatic conditions and exposure to the elements. The best preserved are exhibited in the Archaeological Museum of Laurion.
The decline of Sounion began at the end of the Hellenistic period. By Roman times the two temples had already been deserted. Pausanias describes the monuments in the 2nd century AD, confusing the temple of Poseidon with the temple of Athena, which may indicate the abandonment of the area.
Archaeological excavation of the site in 1906 uncovered numerous artefacts and inscriptions. The 17 early archaic kouroi fragments were found in a deep pit east of the Temple of Poseidon. The statues were probably damaged by the Persians at the time they destroyed the earlier temple. Since they were sacred dedications, they could not be entirely discarded, and thus they were deposited in the pit to make way for newer, undamaged dedications. The best preserved of these statues is a 7th-century BC marble kouros statue known as the Sounion Kouros, now on exhibit in the Athens National Archaeological Museum.
In the 19th century, Sounion was a popular destination for tourists, many of whom engraved their names on the ruins of the temple of Poseidon. The most famous signature is that of the Romantic poet George Lord Byron.
“Place me on Sunium’s marbled steep,
Where nothing, save the waves and I,
May hear our mutual murmurs sweep;
There, swanlike, let me sing and die:
A land of slaves shall ne’er be mine–
Dash down yon cup of Samian wine!”
The Isles of Greece by Lord Byron (1788-1824)
