Thanks, this is the best picture yet! No wonder I walked all over, not being able to find where the Tuileries had stood. It is not where I thought it was at all!
I recall reading that in the Tuileries gardens, while Louis XVI and Marie-Antoinette were in residence during the Revolution, a plot was given to the little Dauphin (Louis XVII) in which he could grow vegetables and flowers. The same patch of ground was used by Napoleon's little boy, the "King of Rome," as his garden and again by young Henri de Cambord several years later. How poignant that three small boys, three princes, who all played in roughly the same area of those vast gardens, were never to sit on the thrones intended for them.
