This writer seems to be on a museum kick this morning, so why stop now? For at least the fourth year in a row, Paris’ Louvre Museum has retained its title as the world’s most popular museum. Late last week, they released their 2010 visitors count, coming in at a whopping 8.5 million, roughly the same as they had in 2009 and 2008 (in 2007, they had just 8.3 million). Though the figures aren’t out yet from the perpetual runner-up, the British Museum (who have usually come in at around 6 million), given that institution’s rocky year, between budget cuts, BP protests, and mysterious gas leaks, we can’t imagine that 2010 was their year to surge ahead, so we’re positive that the Louvre has once again reigned supreme.
