As we consider the monuments of the past which have become landmarks within our scenery, few pictures come more vividly to mind than those of great stone walls winding their way across the skyline. Such constructions were designed to make an absolute statement in terms of power, security, and eternity. When we picture such ancient barriers in competition with one another, we tend to forget that we are dealing with two different leagues.
When we speak of cities and even whole military fortifications throughout parts of Europe, Asia, and the Middle East, all having been encased by huge stonewalls, there is one particular engineering project from East Asia which stands out because of its scale - literally feeling like an achievement of planetary proportions. There is nothing else like it in the world due to sheer length.
