Seven Wonders Of The World

 

CONSTRUCTION OF THE WALL

 

The Great Wall is reputed as one of the seven construction wonders in the world not only for its long history, but its massive construction size, and its unique architectural style as well.

The construction of the Great Wall began between the 7th and 8th centuries B.C. when the warring states built defensive walls to ward off enemies from the north. It was only a regional project then. Until the Qin Dynasty, the separate walls were joint together and consequently it stretched from east to west for about 5000 thousand kilometers and served to keep nomadic tribes out. The Wall was further extended and strengthened in the succeeding dynasties. Especially during the Ming dynasty when the northern nomadic ethnic groups became very powerful, the Ming rulers had the Wall renovated 18 times. As a result, not the remains from the Qin dynasty were restored, but some 1000 kilometers were constructed to a full length of 6,700 kilometers.

The architectural style of the Great wall is a marvel in the history of construction in the world. Since the weaponry only consisted of swords and spears, lances and halberds, and bows and arrows in the ancient times, walls with passes, watchtowers, signal towers, together with moats became an important strategy. To ensure the safety of the dynasties, the feudal rulers strove to improve the construction of the Great Wall after it took shape in the Qin dynasty. In particular, the Ming dynasty saw the creation of a sophisticated defense system along the wall embracing garrison towns, garrison posts, passes, blockhouses, additional wall structures, watchtowers and beacon towers, each given a different status and designed mission. The system enabled the imperial court to stay in touch with military and administrative agencies at various levels, including those at the grassroots, and provided the frontier troops with facilities to carry out effective defense.

The Great wall we see today is mostly from the Ming dynasty. With an average height of 10 meters and a width of 5 meters, the wall runs up and down along the mountain ridges and valleys from east to west. It stands as a witness of the Chinese history, culture and development.
