In this enchantingly beautiful forest with bridges and remains of walls, scenes for Game of Thrones were filmed and we also find light trees, forklifts and signposts to Scene 1 to 3 in the middle of the forest for various shots. We even meet Game of Thrones fans in costumes on a bridge - or were we unnoticed extras in a film?
