Louis XVI Louis D'or Coin

The coin is at the end of this landing.

Louis XVI Louis D'or Coin is a treasure in Uncharted 3: Drake's Deception. It can be found in The Chateau. When the player is in what seems to be the Chateau's main entry way (the room with the large lavish staircases), before climbing through the window, the player should turn around and head down the landing towards the glowing treasure.
