The Acropolis Museum addresses the same issue in a more visceral way, hanging the honey-coloured Greek marbles alongside stark white plaster copies of the British Museum sections.
The Greek government of 1840 had to pay to have these copies made, a quarter of a century after the British parliament authorised purchasing the originals from a bankrupt Lord Elgin. Now they are being used to make the case for reunification in the €130m (£110m) museum. This is architecture as argument.
Although just in case anyone has missed its message, Greek Culture Minister Antonio Samaras is on hand to hammer it home. "For 200 years, the Parthenon Marbles have been amputated, now they must be reunited. The Parthenon frieze speaks through its totality; this voice should be heard not be silenced," Mr Samaras told guests at a special preview. "This museum is creating huge momentum, a global crescendo. We are winning the fight."
