The temple is one of the only two remaining parts on the Olympieion site. The sheer size of this monument is incredible! There is only a few of the original Corinthian columns left of the original 104! This is a perfect site to sit down on a sunny day with a gyro in your hand and just admire it's beauty.
Interesting fact about the Temple of Olympian Zeus is the fact that it took almost 700 years to build. It was started in 515 BC by Peristratos and finished in 125 AD by Roman emperor Hadrian.
Close to the Temple, on Amalias Avenue you can take a closer look at the other remaining monument - Hadrian's Arch, built a few years later by the same emperor. During my visit it was all covered in cellophane for reconstruction, so wasn't very impressive.
