The Ming Dynasty is known for the construction of the Great Wall of China as it's recognized in its present form. The dynasty, which ruled from 1368 to 1644, undertook significant rebuilding and expansion of the Wall to secure the northern borders against invasions by nomadic tribes. The Ming Dynasty's efforts resulted in the construction of the stone and brick structures that still stand today, featuring watchtowers and garrison stations. These enhancements not only fortified military defense but also facilitated trade and cultural exchange along the Silk Road, contributing to China's historical legacy as a powerful empire.
