The 2,600 mile long Great Wall is an amazing structure built to keep out Mongols and other enemies. Initial building was by Emperor Qui in the second century BC, first emperor of a united China ruthlessly using conscripted labour. To add to the fortification it was built along a mountain ridge which made it very steep in places. It is said to be the longest cemetery in the world, workers who died when building it were buried in the wall.
