Olympia, a sanctuary of ancient Greece in Elis, is known for having been the site of the Olympic Games in classical times, the most famous games in history. The Olympic Games were held every four years throughout Classical Antiquity, from the 8th century BC to the 4th century AD. The first Olympic Games were in honor of Zeus. Olympia is an UNESCO world heritage site since 1988.
The sanctuary, known as the Altis, consists of an unordered arrangement of various buildings. Enclosed within the temenos (sacred enclosure) are the Temple of Hera (or Heraion/Heraeum) and Temple of Zeus, the Pelopion and the area of the altar, where the sacrifices were made. The hippodrome and later stadium were also to the east. To the north of the sanctuary can be found the Prytaneion and the Philippeion, as well as the array of treasuries representing the various city states. The Metroon lies to the south of these treasuries, with the Echo Stoa to the East. To the south of the sanctuary is the South Stoa and the Bouleuterion, whereas the West side houses the Palaestra, the workshop of Pheidias, the Gymnasion and the Leonidaion.
Over time the site was buried under alluvial deposits, up to 8 meters deep, long thought to be the result of river flooding. Modern research hypothesizes instead—based on the presence of mollusc and gastropod shells and foraminifera— that the site was buried by ocean waters resulting from repeated tsunamis. The exact site was re-discovered in 1766 by the English antiquarian Richard Chandler. The first excavation of the sanctuary at Olympia was not carried out until 1829, by the French “Expedition Scientifique de Moree“.
The Olympic flame of the modern-day Olympic Games is lit by reflection of sunlight in a parabolic mirror in front of the Temple of Hera and then transported by a torch to the place where the games are held. When the modern Olympics came to Athens in 2004, the men’s and women’s shot put competition was held at the restored Olympia stadium.
