4. Versailles – France
Probably the world's most famous garden, it was built for Louis XIV and designed by Andre Le Notre. The laying out of the gardens required enormous work. Vast amounts of earth had to be shifted to lay out the flower beds, the Orangerie, the fountains and the Canal, where previously only woods, grasslands and marshes were. The earth was transported in wheelbarrows, the trees were conveyed by cart from all the provinces of France and thousands of men, sometimes whole regiments, took part in this vast enterprise.
