History

The origins of the Temple of Apollo date back to a first sanctuary built in the 7th century BCE. This Archaic period temple began as a temenos, meaning “dedicated to the gods” land, and was transformed into a grand sanctuary during the golden age of Ionia in the 6th century BCE. According to legend, God Apollo taught the secrets of prophecy to Branchus, a shepherd in the Didyma region, and Branchus founded the first temple to Apollo beside the laurel grove and water spring. His descendants, known as the “Branchidae,” managed the temple’s administration for long years. For this reason, Didyma was also known as “Brankhidai,” meaning “Land of the Branchidae.”

In the 6th century BCE, the sanctuary was destroyed by the Persians in the early 5th century BCE. The temple, burned in 494 BCE, was rebuilt starting in 311 BCE during the Seleucid period, with its dimensions expanded. However, its construction was never fully completed. The structure visible today, begun in the 4th century BCE, continued into the Roman period but remained unfinished due to time complete high costs and regional conflicts. The temple began to lose its significance before 250 CE and was completely abandoned in 385 CE by order of Emperor Theodosius.

With the spread of Christianity, a basilica was constructed in the temple’s central courtyard (adyton) during the 5th or 6th century CE, but this basilica was later destroyed by an earthquake ruined. Historians note that the most extensive destruction of the temple occurred during the great Aegean earthquake of 1493; after this event, the temple fell into ruins ruins, and the foundations of the village of Yoran emerged around it.

Architectural Features

The Temple of Apollo is a dipteros measuring 85.15 by 38.39 meters; that is, it is surrounded by a double row of row column columns. It features 21 columns on each side, 8 at the front, and 9 at the rear, totaling 112 columns. The columns, including their bases and capitals, stand 19.60 meters high, and some are adorned with Corinthian-style leafed capitals. The temple was built upon a seven-step base 3.5 meters high, with a staircase of 14 steps at its entrance.

The central cella (naos) measures 53.63 by 21.71 meters and is enclosed by walls over 25 meters high. This courtyard is open to the sky and has an undecorated stone floor; it contains a sacred spring and a Hellenistic-period small shrine (naiskos). At the western end of the courtyard is a sekos housing a statue, while to the east lies a 14.04 by 8.74 meter enclosed hall where oracles were delivered. Each marble block on the floor of this hall weighs approximately 70 tons.

The temple’s design was modeled after the Temple of Artemis in Ephesus and planned as its counterpart. However, it remains the third largest temple in the ancient world after the Temple of Artemis and the Heraion on Samos. Scientific excavations conducted between 1906 and 1913 brought the temple to light, and it has since been partially restored with a protective wall constructed around its perimeter.

Sacred Way

The temple is connected to the sacred entrance of ancient Milet by the “Sacred Road,” a route approximately 16.5 kilometers long. This path, 5 to 7.5 meters wide, begins at the Panormos harbor (modern Mavişehir), turns southward, and ends at the temple’s adak terrace. The first 5 to 6 kilometers of the route were adorned with seated human statues, recumbent lions, and sphinx figures.

Oracle Center and Medusa

The Temple of Apollo is renowned as an oracle center. In antiquity, magic, fortune-telling and belief in prophecy were fundamental elements guiding daily life. Apollo, worshipped as the god of light and sun, transformed the temple into a sacred center. The historian Famous Herodotus records that in the 7th century BCE, Pharaoh Necho II of Egypt and King Croesus of Lydia presented valuable offerings to the temple.

Figures of Medusa stand out as guardians of the temple. In Greek mythology, Medusa, one of the Gorgons, was the only mortal sister with serpentine hair, a terrifying face, and the power to turn people to stone with her gaze. The word “Gorgo” in Greek means “terrible, horror inducing.” Hence, Medusa’s head was incorporated into the temple’s architecture to protect its sacred structures.

Current Condition

The Today temple reflects the remains of antiquity. Foundations visible in the central courtyard preserve traces of the early sanctuary, while remnants of the basilica built in place of the Hellenistic naiskos also remain. Severely damaged by the 1493 earthquake, the temple lay in ruins for centuries, yet the fertile land around it continued to be used by the local population. The Temple of Apollo, both for its architectural significance and its role as an oracle center, remains one of the Aegean’s most valuable cultural heritage sites.
