The Great Wall of China is an ancient fortification, built to protect China from various nomadic groups and military incursions. The wall's construction started as early as the 7th century BC, with many Chinese states and dynasties contributing to its development over the centuries. The most well-known sections of the wall were built by the Ming dynasty (1368–1644). The wall stretches from Dandong in the east to Lop Lake in the west, along an arc that roughly delineates the edge of the Mongolian steppe, symbolizing China’s strength and unity.
The Great Wall of China is an architectural marvel, stretching over 13,000 miles. It is constructed from a variety of materials, including stone, tamped earth, wood, and other materials. Its design includes watchtowers for surveillance, fortresses for command posts and logistics, beacon towers for communications, etc. The walls vary in height and width, with the average height being 7.8 meters and the width 4.7 meters, allowing for carriage transportation. The wall is also famous for its uniquely winding path over rugged country and steep mountains.
The Great Wall of China holds immense cultural and historical significance. It is seen as a symbol of the Chinese nation's perseverance, tenacity, and diligence. Besides its military function, the Great Wall also carries a profound cultural connotation, and has long been incorporated into Chinese mythology and symbolism. Some of the wall's parts are even associated with stories and legends, such as the story of 'Meng Jiangnu's Bitter Weeping' which has been passed down from generation to generation.
Today, the Great Wall represents not only China's rich historical and cultural heritage but also its commitment to preserving its history. It is a source of national pride and a testament to ancient China's architectural prowess. The Great Wall continues to be an object of study for historians and archaeologists worldwide, seeking to understand the dynastic histories and technological advancements of ancient China.
Despite common belief, the Great Wall of China cannot be seen from space with the naked eye. It is also a myth that the mortar used in the wall was made from human bones, instead, rice flour was used. The wall is home to numerous species of flora and fauna, some of which are found nowhere else in the world. Despite its length, the Great Wall doesn't have a single continuous line but consists of multiple walls, trenches, and natural defensive barriers such as hills and rivers.
