Olympia is an ancient site on Greece’s Peloponnese peninsula that hosted the original Olympic Games, founded in the 8th century B.C. Its extensive ruins include athletic training areas, a stadium and temples dedicated to the gods Hera and Zeus. The Archaeological Museum of Olympia exhibits finds from the site, including a statue of Hermes attributed to the sculptor Praxiteles. 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), the Temple of Zeus, the Pelopion, and the area of the altar, where the sacrifices were made. Olympia was also known for the gigantic ivory and gold statue of Zeus that used to stand there, sculpted by Pheidias, which was named one of the Seven Wonders of the Ancient World by Antipater of Sidon. Very close to the Temple of Zeus which housed this statue, the studio of Pheidias was excavated in the 1950s. Evidence found there, such as sculptor’s tools, corroborates this opinion. The ancient ruins sit north of the Alpheios River and south of Mount Kronos (named after the Greek deity Kronos). The Kladeos, a tributary of the Alpheios, flows around the area.
