Two large ancient city ruins were found in Xinzheng, Henan Province. The discoveries are historically significant because they date back to China's Xia and Shang Dynasties, which are the first and second recorded dynasties dating back over 4,000 years. Let's have a look.
Cultural Relics and Archaeology Research Institute of Zhengzhou in Henan Province announced that the two large city ruins covered a total area of 1.68 million square meters.
Shang dynasty architects built their city on top of the Xia city ruins. The Shang city was not as large as its predecessor, so to separate itself from the ruins surrounding their new city, they built a moat and wall for protection. Researchers also discovered that the Xia city planners also had thier own moat and wall.
