The Temple of Olympian Zeus (Olympeion) was the most ambitious building project of ancient Agrigento, begun to celebrate a famous military victory and never finished. Today it lies in a dramatic field of tumbled column drums and architectural fragments — the deliberate ruin of something that was immense. The reconstructed telamon, a 7.5-metre giant figure that served as a column support, lies flat on the ground in the western section of the Valle dei Templi park, giving a visceral sense of the temple's scale.
The structure would have been unlike any other Doric temple: between its columns stood these colossal Atlas figures supporting the entablature, while the outer colonnade itself was engaged (attached to the walls) rather than free-standing. The original design appears never to have been tested in practice. The site is within the archaeological park and best understood with a guide or at minimum the excellent bilingual information panels.
