Explore the engineering, geometry, and physics behind seven ancient Chinese fortresses that defied siege warfare, heavy artillery, and brutal weather conditions. From Diaoyu Mountain's water-bearing sandstone plateau that stalled the Mongol Empire to the polymer-bonded sticky-rice mortar of the Nanjing City Wall, these military strongholds weaponized natural landscapes and physics to hold off overwhelming armies. Discover how defensive masons utilized wide moat mechanics, narrow choke points, thermal insulation, and gravity to build strongholds that altered world history.
