Grotte du Serment

Highlight • Gorge

The Oath Cave 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 Folie Denecourt".

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".
