The Chateau Royal de Blois comprises several buildings constructed from the 13th to the 17th century around a central courtyard.
Each of the wings is of a different architectural style, typical of many 17th century Loire Valley chateaux.
It has been the residence of 7 kings and 10 queens of France.
Largely abandoned after 1660, it was ransacked during the revolution and later scheduled for demolition.
The chateau was saved by King Louis-Philippe in 1841 when it was classified as an historic monument and subsequently restored.
The Cour du Cheval Blanc of Fontainbleau is also known as the Courtyard of Farewells.
The Courtyard of Farewells commemorated the leavetaking ceremony at the foot of the staircase in honor of the Emperor Napoleon I when he left Fontainebleau for the Island of Elba in 1814.
The initial project for building the castle of Chambord was based on the shape of a Greek cross.
Repeated on each floor, the symmetry of the apartments had four towers, four square apartments and a large hall in the form of a cross.
BTW - has anyone used Google Maps to take a tour - on the outside - of Versailles? One can actually go down small roads - I've done it a few times - and once actually and very unexpectedly came upon Marie Antoinette's Hameau de la Reine - amazing - I wasn't even looking for it and there it was! I could spend hours doing that.
