Regarded as one of the world's most famous landmarks, the Great Wall of China is believed to be the most extensive construction ever carried out. This vast landmark is a product of the combined effort of dynasties since its construction in 7th Century BC, under the Zhou Dynasty, when states established their own walls as a defense.
Through the order of Emperor Qin Shi Huang (221-207 BC) and spearheaded by the then-Chinese general Meng Tian, the 10-000-Li-Long Wall was built to connect and extend to the other walls of former state to serve as a fort from the barbarian nomads attempting to cross into the Chinese Empire. The workforce, which was said to be around 400,000 individuals, was mainly composed of soldiers, prisoners, and commoners.The ancient wall relics, comprised of trenches, fortresses, and towers, span evenly throughout 15 provinces and regions.
This largest man-made construction in China was recently recorded with a total length of 13,170.6956 miles. Through the centuries, some portions of the wall are already in poor condition while only a small section of the original structure remains whole. The last renovations and extension were carried out by the Ming Dynasty through the 14th-17th Century. The 8,851.8-km Ming Great Wall is known to be the most popular and well-preserved among the rest.
