The mirrors
Seventeen arches of mirror face the seventeen windows, made of more than 350 panes. Mirror glass was a costly luxury, and making it in France broke Venice's monopoly.
An interior photograph with its features marked, each comparing the room with its paintings and history.
The same content as the picture, as text: every part and what it says when you open it.
Seventeen arches of mirror face the seventeen windows, made of more than 350 panes. Mirror glass was a costly luxury, and making it in France broke Venice's monopoly.
Painted under Charles Le Brun: thirty scenes celebrating the first two decades of Louis XIV's personal rule. At the centre, The King rules by Himself, 1661.
Crystal chandeliers hang the whole length of the gallery. In Louis XIV's day they held candles, and the mirrors doubled every flame.
Antique gods and Muses - Venus, Bacchus and Diana among them - stand in the niches, with marble and porphyry busts of eight Roman emperors.
The tables and stools are mostly 19th-century. The original furniture was solid silver, and Louis XIV had it melted down in 1689 to pay for a war.
Gilded statues stand along the gallery, each holding up a candelabrum of crystal.
At the far end, the Salon of Peace; at the other, the Salon of War. The gallery joined the King's apartments to the Queen's.
Every window looks west over the gardens, and in the afternoon the sun lays their pattern across the parquet.
The German Empire was proclaimed in this room in 1871. In 1919 the treaty that ended the First World War was signed in the same room - by design.
