My mom just called to say she read an article that listed the five most-visited museums in the world and wanted to know if I've visited them all. Yeppers!
Here's the list:
Louvre in Paris, with 8.5 million visitors (I visited in 2001 and 2008)
British Museum in London, with 5.9 million (2001 and 2008)
National Gallery of Art in Washington, with 4.96 million (last visit was in college)
Tate Modern in London, with 4.95 million (2001)
Metropolitan Museum of Art in New York, with 4.82 million (a couple years ago)
I'd also add the Freer Gallery in D.C. (lovely Japanese and American art) and Musee d'Orangerie in Paris (displays Monet's water lilies in a 360-degree-view) to my top personal list.
