The Versailles Orangerie (French: L′Orangerie du Château de Versailles) was built by Jules Hardouin-Mansart between 1684 and 1686, replacing Le Vaus design from 1663 - that is to say, before work on the palace had even begun. It is an example of many such prestigious extensions of grand gardens in Europe designed both to shelter tender plants and impress visitors. In the winter, the Versailles Orangerie houses more than a thousand trees in boxes. Most of them are orange trees.
