Versailles Orangerie

The Versailles Orangerie was built by Jules Hardouin-Mansart between 1684 and 1686, replacing Louis Le Vau’s design from 1663 – that is to say, before work on the Château 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. Louis XIV's gardens were no longer just a sanctuary for him to stroll through, but now the theatrical setting to entertain guests at court.
