2. It took over 2,000 years to construct
The Great Wall as we know it today was built over the course of five dynasties. The first emperor of China, Qin Shi Huang, took the remnants of ancient fortifications, walls, and earthworks and linked them into a unified wall around 220 BC. Because of climate conditions and human activities, a third of this UNESCO World Heritage site — approximately 2,000km — has already disappeared. Still, many sections of the wall are being restored as we speak — see for yourself by taking a hike now.
3. It’s not just a wall — it’s a whole defense structure.
The Great Wall is not a single-structured wall. It includes beacon towers, barriers, barracks, garrison stations and fortresses along the walls. Together, they form an integrated defense system.
“Walk the Great Wall of China” includes a feature on the western starting point of the Great Wall during the Ming Dynasty. Tragically, all that remains today is a lonely earthen mound.
