Did the Construction of the Great Wall Refer to Foreign Fortifications?

The Great Wall of China stands as a remarkable and unique architectural achievement. While it is predominantly a product of Chinese innovation and engineering prowess, there is little evidence to suggest direct reference to foreign fortifications. China's development of the Great Wall was driven by its own historical context, with the need to defend against nomadic incursions from the north. Over centuries, Chinese builders refined their techniques, evolving from simple earthen walls in the early days to the magnificent brick and stone structures we know today. The design was tailored to the local terrain, incorporating mountains, valleys, and plains to create an effective defense line. Although trade and cultural exchange existed with other regions, the core concepts and construction methods of the Great Wall seem to have been homegrown, reflecting the creativity and determination of the Chinese people to safeguard their homeland.
