Work on the wall started in 500 BC during the rule of the first Chinese emperor, [[Qin Shi Huang]], and continued for 2,000 years. Most of the work was done during the [[Ming Dynasty]]. At regular intervals towers were built; at first they functioned purely as watchtowers but later on they were modified to include [[cannon]]s and defenses against aerial attacks.
