A concrete wall extends across the territory of the Korean peninsula, dividing it into the north and the south.
The wall stands 27 km east of Kaesong. It was built for several years from 1977 along the Military Demarcation Line by the south Korean authorities for the purpose of perpetuating the division of Korea. It is a trapezoidal structure, measuring 5-8 m high, 3-7 m wide at the top and 10-19 m wide at the bottom. More than 800 000 tons of cement, 200 000 tons of steel and 3.5 million cubic metres of sand and gravel were used to build it.
Now it reveals the anti-national and anti-reunification crimes of the south Korean authorities.
