as of 2012 , NYU operates 12 academic sites in Africa, Asia and the Middle East, Australia, Europe, North America, and South America, including undergraduate academic-year and summer study abroad programs in Accra, Berlin, Buenos Aires, Florence, London, Los Angeles, Madrid, Paris, Prague, Sydney, Tel Aviv, and Washington, D.C. One of the most noteworthy is the 57 acres campus of NYU Florence Villa LaPietra in Italy, bequeathed by the late Sir Harold Acton to NYU in 1994, that at the time was the largest donation to a university in history.
