The great wall covered in snow
It is estimated that the length of the great wall is about 9000 kilometers. It was built from the 3rd century BC (about 215 BC) by Emperor Qin Shi Huang of the Qin dynasty. It’s the same Emperor to whom we owe the so-called terracotta army in Xian. Sections of the great wall were added in later centuries, but it was during the Ming dynasty in the 14th and reached its current dimensions. Bricks and stones were used rather than clay, stone and wood.
