Dive-site story
Submerged during the construction of the Panjiakou Reservoir in the late 1970s, this site offers a surreal encounter with Ming Dynasty stone fortifications preserved beneath the surface. Divers trace ancient ramparts, battlements, and watchtowers that once formed part of the Great Wall's border defenses. Silt accumulation and sharp thermoclines define the ambient diving environment, demanding precise buoyancy control to preserve visibility across the centuries-old stonework.
