The empire famously associated with the construction of the Great Wall and the Silk Road is the Chinese Imperial Empire, particularly during the Qin and Han Dynasties. The Great Wall was constructed to protect against invasions, while the Silk Road facilitated trade and cultural exchanges between East and West. This empire played a crucial role in shaping the economic and cultural landscape of Asia, connecting various civilizations and enabling the flow of goods, ideas, and innovations. The legacy of these infrastructural achievements endures in modern China.
