On a list of ‘must sees’ for most visitors to Paris, along with the obvious sights such as the Eiffel Tower, the Louvre etc., is likely to be the Château de Versailles. Far less familiar though is the Château de Fontainebleau, arguably the centre of the history of French monarchy. No site in France can compare as a royal residence. It predates the Louvre itself by 50 years, and Versailles by 5 centuries.
Fontainebleau is the only château that was lived in by every French monarch for almost 8 centuries.
