The Great Wall of China is one of the most remarkable constructions ever built in the Ancient ages. It is a wall that stretches for thousands of miles along China's northern border. No other Wonder of the Ancient age had such a large size. The amount of money and time the Chinese spent on building as well as maintaning with troops over the centuries with this one defensible wall was a  staggering cost probably the eqivelent of a trillion US dollars over the centures that the varius Chinese governments spent on it. But eventually through the dedicated leaders the Chinese achieved this goal of a fully built and manned wall.
