The Great Wall, also known as the Wall of 10,000 Li, is the world's longest wall and one of China's most famous landmarks. It stretches over 13,000 miles from Shanhaiguan in the east to Jiayuguan in the west, and was built over a period of more than 2,000 years.
The Great Wall was constructed to protect China from invading armies and to control trade along the Silk Road. The earliest sections of the wall were built in the 7th century BC, during the Warring States period, and were made of rammed earth and stone. These early walls were not continuous, but rather a series of fortifications that were built and rebuilt over time.
The most famous sections of the Great Wall were built during the Ming dynasty (1368-1644). These walls were made of brick and stone, and were built to be more durable than the earlier walls. They were also built to be higher and wider, with watchtowers and fortresses spaced at regular intervals along the wall.
The Great Wall was built using a variety of techniques, including brick and stone masonry, rammed earth, and tamped earth. The walls were typically built on ridges and hills, and followed the natural contours of the land. The materials used to build the wall were sourced locally, and included granite, limestone, and sandstone.
The construction of the Great Wall was a massive undertaking that required the labor of millions of workers. It is estimated that up to 1 million people died during the construction of the wall, many of whom were buried within the wall itself.
Today, the Great Wall is one of China's most popular tourist attractions, drawing millions of visitors each year. It has also been designated as a UNESCO World Heritage Site, and is considered one of the Seven Wonders of the World. Despite its fame, however, the Great Wall remains a symbol of the challenges and sacrifices that were required to protect China from its enemies.
