Small cave in the woods, with engravings, in homage to Samuel Adam-Salomon - French sculptor of the 19th Century who spent most of his life in Fontainebleau. His works are mainly exhibited at the Musée d'Orsay, the Invalides and the Chateau de Versailles.

The cave of the oath is quite surprising, especially because the vault is made of a single rock. The letters D.F.D were engraved on the cave by Denecourt himself and mean "Last Madness Denecourt".

Here is another superb view of the forest of Fontainebleau, on the Barbizon side. The panorama over the Gâtinais is truly magnificent, with trees as far as the eye can see.
