The Great Wall was key to protecting agricultube and resisting cavalry of the .uns and other warrior tribes from the north. The advantages of the enormous barrier diminished with the advancement of gunpowder and other weaponry.
The wall was originally built of stone, wood, grass and earth. In the Ming Dynasty bricks were produced in kilns set up along the wall. The bricks were transported by men carrying them on their backs, donkeys, mules and even goats had a brick tied to their head before being driven up a mountain.
