The Acropolis Museum in Athens communicates this theft very effectively and poignantly. The top floor is 1:1 scale to the original Parthenon. All the marbles are shown, including both the ones Greece has and the stolen marbles reconstructed in a bright white plaster. Just walking through and looking at it all you can feel the sense of loss and injustice.
