The Grand Canal of China is the world's oldest and longest canal, far surpassing the next two grand canals of the world: Suez and Panama Canal.
The building of the canal began in 486 B.C. during the Wu Dynasty. It was extended during the Qi Dynasty, and later by Emperor Yangdi of Sui Dynasty during six years of furious construction from 605-610 AD
The canal is 1,795 Km (1,114 miles) long with 24 locks and some 60 bridges.
