Chosen in 2007 as one of the "New Seven Wonders of the World," the Taj Mahal sees as many as 70,000 visitors in a single day— it was getting so unmanageable that officials instituted a 40,000-person daily cap back in January. Many also complain that the attraction is filled with "tour guides" and "photographers" who nag visitors and then deliver less-than-satisfactory services.

All of that aside, though, this perfectly symmetrical white marble mausoleum is a beautiful symbol of India, and a trip to the country without seeing it up close would be incomplete.
