Default How was the Great Wall of China built?

The earliest Great Walls were built using layers of rammed (compacted) earth, sometimes strengthened with reeds. Later walls were built – sometimes using the earlier walls as a base – using adobe or with combinations of stones and very durable bricks with mortar. Millions of workers contributed to the highly complex and labor-intensive creation of the Great Wall.
