Tourist hotspots like the canals of Venice and the Louvre in Paris should be digitally replicated as a way to tackle overcrowding, a Swiss economist says.
Bruno Frey, 79, a professor at the University of Basel, has written a book called Venedig ist uberall (Venice is Everywhere).
In it, he says technologies like holograms, augmented reality (AR) and multimedia experiences could replicate tourist locations 'even better than the originals'.
Technologies could not only replicate buildings like museums, but the precious historical artefacts that are housed within them.
The digital hotspots would be near to the original locations and try to recreate the sounds and smells, bolstered by exciting and immersive media presentations.
