China || The Grand Canal is a vast waterway system in the north-eastern and central-eastern plains of China, running from Beijing in the north to Zhejiang province in the south. Constructed in sections from the 5th century BC onwards, it was conceived as a unified means of communication for the Empire for the first time in the 7th century AD (Sui dynasty). This led to a series of gigantic construction sites, creating the world’s largest and most extensive civil engineering project.
