LEONARDO da Vinci’s Last Supper, the Trevi Fountain in Rome, Stonehenge, the Hermitage Museum of art treasures in St Petersburg are all buckling under the weight of a global tourism boom.
And in response to the onslaught, the countries that own these wonders are removing them from view, or at least erecting barriers or restricting access to protect them.
Under the stampeding hordes of curious travellers, not to mention drunk tourists, these irreplaceable antiquities have been chipped, cracked or threatened by mere breathing.
In the Italian city of Milan, for example, Leonardo da Vinci’s’s great masterpiece The Last Supper is still open to small private tour groups to view with the naked eye.
But not for long.
