Located in Diebu County, Gannan Gansu, Zhagana Stone Box or Zhagana Stone Mountains Fortress is hailed as "Eden of Adam and Eve" by explorer Joseph Rock for a breathtaking natural stone fortress and four ancient Tibetan villages at an altitude of 3,000 meters.   

Surrounded by towering cliffs and snow-capped peaks, this stone city enshrines four ancient Tibetan villages—Dongwa, Yeri, Dari and Daiba—along with Lhasang Monastery. Carved by Quaternary glaciers, its jagged rock formations, primeval forests and alpine meadows create a fairy-tale landscape.

Wandering through, you'll find traditional wooden Tibetan houses, fluttering prayer flags and smoke curling from hearths. At dawn, sea of clouds drifts among peaks; at dusk, golden sunlight bathes the stone city. A perfect blend of raw natural beauty and authentic Tibetan culture, Zhagana is a hidden paradise on the Qinghai-Tibet Plateau's edge.
