Athens’s New Acropolis Museum opened in 2009 with at least two missions: to display Acropolis artifacts in a modern setting and to regain the missing Parthenon Marbles, removed from the ancient building in the early 1800s by Lord Elgin and sold to the British Museum in England shortly after. The British Museum long argued that Athens didn’t have a venue fit for them. That’s no longer the case, with this state-of-the-art, three-story glass structure at the foot of the Acropolis floating on stilts above the ruins of a sixth-century Athenian neighborhood. The museum holds more than 4,000 artifacts, including five of the six original caryatids returned by Britain, but its crown glory is the Parthenon Gallery, overlooking the temple itself and housing the Parthenon frieze, with temporary replicas filling in the still-missing metopes. The British Museum has yet to agree to return the metopes and the sixth caryatid—an ongoing controversy.
