On July 22 I went hiking in Shuitoucun with à group of various nationalities for discovering the wild Great Wall alone in the nature. The walk to get at the top was quiet difficult, it was hot and some passages in the bush were very steep but after a few hours we could reach the top of a first hill and imagine how difficult it was to build this amazing construction. It was a real strong defensive wall as it follows the top of all the hills and cliffs. I could make some fantastic photos with my paper Stella for my concept « memory of the geography of time ». A great moment passed in a very interesting and nice company even if I‘ve suffered of this intense effort in an hostile, nearly inaccessible area.
