The temple of Zeus Olympios, built in 470-460 BC by the architect Libon of Elis, is the largest temple of the Peloponnese (about 64x28 meters, with a height of 20 meters). It was built in shell limestone covered by imitation marble stucco. The temple stands on a sturdy crepidoma with three steps breached by an access ramp on the east side. The cella and other rooms as well as the impressive remains of the peristasis (6x13 columns) provide a good idea of the temple's imposing dimensions.
