The Temple of Olympian Zeus, also known as the Olympieion, is located just 500 meters southeast of the Acropolis and approximately 700 meters from Syntagma Square. It is not just an ancient temple, but the largest temple in ancient Greece, whose construction stretched over an incredible 650 years — from the 6th century BC to the 2nd century AD.
Unlike the Parthenon, which was built in just 15 years, the Olympieion became a symbol of ambition, decline, oblivion, and finally the triumph of one man`s will — the Roman emperor Hadrian, who completed what neither Greek tyrants nor Hellenistic kings could finish.
Today, 15 columns remain of the grand structure (one more column was felled by a storm in 1852). But even these ruins give an idea of the scale of the design: the columns reach 17 meters in height and 1.7 meters in diameter. For comparison: the columns of the Parthenon are only 10.4 meters high.
Construction History of the Temple of Olympian Zeus
Beginning under the Tyrants (6th century BC)
Construction of the temple began around 515 BC under the Athenian tyrant Peisistratus the Younger. The plan was truly grand: the tyrants wanted to surpass the two most famous temples of their time — the Heraion of Samos and the Temple of Artemis at Ephesus. The architects of the project were Antistates, Callaeschrus, Antimachides, and Porinus.
The temple was conceived in the Doric style, on a platform measuring 41 by 108 meters, with a double colonnade: 8 columns on the facade and 21 on the sides. However, work was abandoned after the overthrow of the tyranny and the expulsion of Hippias in 510 BC.
Oblivion in the Era of Democracy
Under Athenian democracy, the temple remained unfinished. The Greeks believed that construction on such a scale was "hubris" (pride) that offended the gods. Aristotle, in his "Politics," cited the Temple of Zeus as an example of how tyrannies occupied the people with great projects, leaving them no time, energy, or means for rebellion.
Themistocles, one of the greatest statesmen of Athens, even used parts of the unfinished temple to build a defensive wall connecting Athens to Piraeus. A section of this wall can be seen next to the temple even today.
Revival under Antiochus IV (2nd century BC)
The next attempt to complete the Temple of Olympian Zeus was undertaken in 175–164 BC by the king of Hellenistic Syria, Antiochus IV Epiphanes. Antiochus, who considered himself the earthly incarnation of Zeus, entrusted the direction of the work to the Roman architect Decimus Cossutius.
The project was radically changed:
• The architectural order was changed from Doric to Corinthian — for the first time in history, this order was used on the facade of a major temple
• The number of columns was increased to 104
• On the facades there were to be 8 columns in three rows, on the sides — 20 columns in two rows
• The material was changed to expensive Pentelic marble
However, in 164 BC, Antiochus died, and construction stopped again. The temple remained unfinished for almost another three centuries.
Looting by Sulla
In 86 BC, the Roman dictator Sulla captured Athens. He removed several carved capitals from the columns of the Temple of Olympian Zeus and sent them to Rome to decorate the Temple of Jupiter Capitolinus. Despite this looting, the Roman historian Livy, almost a century later, called the Athenian temple of Zeus "the only one in the world worthy of that deity."
Completion under Hadrian (2nd century AD)
The Temple of Olympian Zeus was finally completed only under the Roman emperor Hadrian, a passionate admirer of Greek culture. Hadrian loved Greece so much that, contrary to all imperial rules, he even let his beard grow to look like Greek philosophers.
In 124–125 AD, during his visit to Athens, Hadrian began a large-scale building program. A marble enclosure was built around the temple, a paved square was created, Roman baths and a monumental arch (Hadrian`s Gate) 18 meters high were built. The consecration of the temple took place in 132 AD and became the central event of the Panhellenic festivities. Hadrian dedicated the temple to Olympian Zeus and adopted the title "Panhellenios" (All-Greek).
Architecture of the Temple of Olympian Zeus
In its final form, the temple had the following dimensions:
• Length: 110.35 meters
• Width: 43.68 meters
• Total number of columns: 104
• Column height: 17.25 meters
• Column diameter: 1.7 meters
The temple`s layout was dipteral (with two rows of columns around the perimeter) with an additional third row on the narrow sides. The interior space was divided into three parts: the front portico, the cella (sanctuary), and the rear portico.
Corinthian Capitals of the Temple of Olympian Zeus
The capitals of the columns are a masterpiece of stonemasonry. Each capital is carved from two massive blocks of Pentelic marble and decorated with stylized acanthus leaves — a characteristic element of the Corinthian order. It was these capitals that so amazed contemporaries with their beauty and craftsmanship.
Statues Inside the Temple
Inside the cella stood two colossal statues:
• Statue of Zeus — executed in the chryselephantine technique (of gold and ivory). This archaic method of manufacture for the 2nd century AD was a conscious imitation of the famous statue of Athena Parthenos in the Parthenon by Phidias.
• Statue of Hadrian — the emperor was equated with Zeus and honored with his own statue of the same size inside the temple.
Pausanias, who visited the temple in the 2nd century, describes it as "worthy of admiration," noting that the statue of Zeus is second in size only to the colossi of Rhodes and Rome.
Destruction and Decline of the Temple of Olympian Zeus
Invasion of the Heruli (267 AD): The temple`s glory was short-lived. In 267 AD, Athens was invaded by the Germanic tribe of the Heruli. The barbarians looted and burned the city. The Temple of Zeus was severely damaged and probably never restored.
Christian Era: After Emperor Theodosius I banned pagan cults (end of the 4th century), the temple fell into complete desolation. Elements of the temple were used for the construction of Christian churches and residential buildings.
Middle Ages and Ottoman Period: By the end of the Byzantine period, the temple was almost completely destroyed. When the Italian traveler Cyriac of Ancona visited Athens in 1436, he counted only 21 surviving columns out of the original 104.
In 1759, the Turkish governor of Athens, Mustafa Agha Tzistarakis, who was building a mosque in the Monastiraki district, blew up one of the temple`s columns to obtain marble for lime production. A Greek inscription on one of the surviving columns reads: "On April 27, 1759, he destroyed the column." During the Ottoman period, the Greeks called the ruins "Hadrian`s Palace," and the Turks called it "Palace of Belkis" (according to legend, the temple was the residence of Solomon`s wife).
Earthquake and Storm (5th century and 1852)
The Temple of Olympian Zeus was completely destroyed by an earthquake in the 5th century AD. The last of the standing columns was felled by a strong wind in 1852 and today lies on the ground, divided into drums. Today, the temple grounds are part of the unified archaeological zone of Athens and are protected by the Greek Ministry of Culture.
The Temple of Olympian Zeus Today: What Has Survived
• 14 columns in the southeastern corner — the most impressive fragment, forming one corner of the temple
• 2 free-standing columns in the southwestern corner
• 1 fallen column (fell in 1852), whose drums are picturesquely scattered along the line of its fall
A total of 15 columns out of the original 104. Yet even these ruins give a clear idea of the scale of the structure. The columns reach 17 meters in height — that is the height of a 6-story building.
Next to the temple, you can see an excavated section of the Themistoclean Wall — a defensive structure built in 479–478 BC to protect Athens from the Persians. Parts of this wall were built from blocks of the unfinished Temple of Zeus.
The Temple of Olympian Zeus is a monument not so much to the gods as to human ambition and persistence. Six and a half centuries of construction, several empires that succeeded each other, dozens of rulers who dreamed of completing this colossus — and only Hadrian, a philhellene on the Roman throne, managed to put an end to it.
Today, looking at the 15 columns towering over modern Athens, it is difficult to imagine the scale of what was planned. But even these ruins are among the most impressive in Greece. They remind us that greatness is not always measured by completion. Sometimes the very attempt to build something grandiose, even if it stretches over centuries, becomes a legend.
