Conquest of the Great Wall of China.

Great Wall of China - the largest building ever undertaken by humans.

There, behind the Great Wall of China
completely different world -
nomadic world , ruthless, steppe ,
Forever threatening war.
Wild hordes of an uproar over her.
each spring all dreadful
crazed horses hooves
Whirlwinds of sand and stones ...

Ibid in the Wall have found their last resting place of hundreds of thousands of workers who died from overwork during construction.
