The Great Wall is by far and away one of the most awesome structures I have ever seen. Portions of it were started as early as 200 B.C., and its construction continued through the 16th century. It is estimated that nearly three billion people died in the building of this massive fortification, and at its peak, it was guarded by more than one million men. Standing atop the Wall at sunrise, I not only felt small in relation to the sheer size and magnitude of this structure that stretches on for over 4,000 miles, but also in terms of historical significance. The Great Wall has outlasted any individual human lifespan hundreds of times over. I wonder what the ancient Mongols would have thought about the automated tram that carries tourists to the top or the alpine slide provided as a fast-paced ride back down.
