Overview
The Great Wall of China is a vast system of walls and fortifications built over several centuries, intended to protect northern Chinese states from invasions. Construction began as early as the 7th century BC, with major sections built during the Qin, Han, and Ming dynasties.
Stretching over 21,000 kilometers, the wall is the longest man-made structure in the world. It was constructed using stone, brick, tamped earth, and wood, depending on the region and era.
Today, the Great Wall stands as a symbol of Chinese ingenuity, determination, and historical identity, and it remains one of the most visited cultural landmarks on Earth.
