Olympia (Greek: Olympí'a or Olýmpia, older transliterations, Olimpia, Olimbia), a sanctuary of ancient Greece in Elis, is known for having been the site of the Olympic Games in classical times, comparable in importance to the Pythian Games held in Delphi. Both games were held every Olympiad (i.e. every four years), the Olympic Games dating back possibly further than 776 BC. In 394 emperor Theodosius I abolished them because they were reminiscent of paganism.
