Temple of Juno, Ancient Greek temple in Valle dei Templi, Agrigento, Italy

The Temple of Juno is an ancient Greek temple featuring 34 Doric columns, with six at the front and back and thirteen along each side, situated on a natural platform. The structure measures approximately 38 by 17 meters and includes a monumental altar on its eastern side with visible traces of reddish stones marked by ancient fires.

Construction of the temple began around 450 BCE during the prosperous period of ancient Akragas and it suffered major damage from Carthaginian forces in 406 BCE. The Romans later undertook reconstruction efforts, incorporating the structure into their own rule.

The temple's traditional name links it to Hera, though its dedication to Athena has been established. In front of the eastern front stood a monumental altar where rites took place. The building was restored in Roman times, when its terracotta roof tiles were replaced with marble ones and a ramp was added to the eastern front.

The temple sits on elevated ground within the archaeological site, offering good views from many vantage points. Visiting in the morning is rewarding, as the area is less crowded and the light beautifully illuminates the columns.

The Doric columns display mathematical proportions so precise that they influenced temple architecture across the Mediterranean for centuries afterward. This system of proportions was studied and replicated by builders in later periods.
