Korean Demilitarized Zone
In the area south of the Military Demarcation Line, which cuts across our country at its waist, there is a concrete wall which [...] stretches more than  from east to west, is  high,  thick at the bottom, and  wide in the upper part. It is set with wire entanglements and dotted with gun embrasures, look-outs and varieties of military establishments [...] the South Korean rulers built this wall over a period of many years from 1977.
