A somewhat vague (tantalizing?) piece from the Athenian News Agency:

Greek Alternate Culture Minister Fani Pali-Petrallia signed a memorandum of cooperation with IAAF over the weekend in Florence envisioning the founding of a World Museum of Classical Sport in Greece.

She presented IAAF with a plan for the establishment and operation of the new museum, expected to be housed at the International Broadcast Centre (IBC) at Maroussi in northern Athens.

Pali-Petralia noted that "the signing of the memorandum is of particular importance to Greece, giving us the possibility to found a museum of classical sport..."

... that's all there is.
