One of the Greek statues in the Parthenon collection at the British Museum. The Greek government has long argued that all the statues should be returned to Athens. In light of their current financial woes perhaps they could be adequately financially compensated. Other museums that hold sculptures from Parthenon are:
Musée du Louvre, Paris, Vatican Museums National Museum, Copenhagen Kunsthistorisches Museum, Vienna University Museum, Würzburg Glyptothek, Munich.
If they all paid allowing for 200 yrs interest that should just about solve the Greek woes.
