Katakolon is gateway to ancient Olympia, the chief sanctuary of Zeus. After many centuries of competition which began as early as the eighth century BC, the panhellenic festival was created in 776 AD. Ancient competitions included boxing, wrestling, running, jumping, and the discus throw. It is still honored with the Olympics Games every four years. The ancient site of Olympia is also home to the Temple of Zeus, one of the Seven Wonders of the World.
