What materials was the Great Wall of China built out of?

Made mostly of earth and stone, the wall stretched from the China Sea port of Shanhaiguan over 3,000 miles west into Gansu province.

Bricks were more advanced materials than earth and stone as their small size and lightweight made them convenient to carry and thus quickened the speed of construction. Bricks are also the ideal material to bear weight. Therefore, bricks were used as the upper layers of the walls to resist attack from various weapons.
