The official figures for 2010 show that the New Acropolis Museum was the most popular site for tourists visiting Greece. The British Museum might claim that more people see the Elgin Marbles in London (a fact that is open to some debate), however in the case of the New Acropolis Museum, the figures are for those people purely wanting to see the marbles – not general figures for a museum, which may include the Duveen Gallery, amongst numerous other elements.

Acropolis Museum is Greece’s top site: official data
(AFP) – Apr 11, 2011
ATHENS — The Acropolis Museum was Greece’s top tourist draw in 2010, eclipsing for the first time the ancient Athens citadel whose sculptures it showcases, official data showed on Monday.
Over 1.3 million people queued to visit the country’s newest museum between January and December last year, the Greek statistics authority (Esa) said.
Designed by Franco-Swiss architect Bernard Tschumi, the ultra-modern building lies within sight of the ancient Acropolis citadel and showcases sculptures from the golden age of Athenian democracy in the fifth century BCE.
By comparison, the Acropolis citadel itself drew just over 990,000 people last year after being hit with several strike shutdowns in a broader protest movement against unpopular austerity cuts imposed by the debt-hit government.
Inaugurated in June 2009, the new museum includes a section reserved for the disputed Parthenon Marbles, currently at the British Museum in London.
Greece has long pursued a campaign for the return of the priceless friezes, removed in 1806 by Lord Elgin when Greece was occupied by the Ottoman Empire, which the British Museum refuses to repatriate.
The Greek statistics authority said overall attendance in 2010 had increased by 11.5 percent at the country’s museums and fallen by 7.1 percent at archaeological sites.
Museum income increased by 31.7 percent compared to the same 12-month period in 2009 while site revenues dropped by 8.8 percent, Esa said.
Tourism proceeds are a major source of income for Greece which is battling to emerge from recession after a narrow brush with bankruptcy last year.
