While people may have been flocking to the Pyramids since, well, 5,000 years ago, Smithsonian Magazine has put together a list of the top 20 new tourist destinations future generations might add to their bucket lists.
Sites of recent scientific, artistic and historical importance such as CERN, home of the God-particle, and the world's fastest rollercoaster in Abu Dhabi are among those that make the cut.
