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, dating back to 776 BC. In 394 AD, emperor Theodosius I abolished them as they were then considered reminiscent of paganism. The first Olympic Games were in honor of Zeus.
Archaeological Site of Olympia is a UNESCO World heritage site
