Greece hopes to regain the ancient sculptures from the British Museum, which were taken from Athens two centuries ago by the Earl of Elgin.
Tamasin Ford is given a personal tour of the marbles by the museum. But Dr Elena Korka of the Greek Ministry of Culture expresses the outrage felt by her country at the loss of these national treasures, including statues that were physically dismembered in order for sections to be carted away.
Both sides assert a legal right to the marbles, although the matter has yet to be definitively settled. We hear the claims and counter-claims from barrister Geoffrey Robertson, as well as from Dr Tatiana Flessas, associate professor of law and the London School of Economics.

Quantum computers: What are they good for?
Google claims to have achieved a major breakthrough with "quantum supremacy". But what could quantum computers actually do, and how soon will they be useful?
Manuela Saragosa speaks to Harvard quantum computing researcher Prineha Narang, who says that the devices she is working on are annoyingly "noisy", but could still make an important contribution to tackling climate change in the next few years.
There are fears that quantum computers could one day crack modern encryption techniques - rendering private communications and financial transactions unsafe. But IBM cryptography researcher Vadim Lyubashevsky says don't worry, they've got the problem in hand.
Plus, the BBC's technology correspondent Rory Cellan-Jones delineates the greatest paradox of quantum computers - that nobody can explain how they work.
