Yinxu is the site of one of the ancient and major historical capitals of China. It is the source of the archeological discovery of oracle bones and oracle bone script, which resulted in the identification of the earliest known Chinese writing. The archeological remnants (or ruins) known as Yinxu represent the ancient city of Yin, the last capital of China's Shang dynasty which existed through eight generations for 255 years, and through the reign of 12 kings. Yinxu was discovered, or rediscovered, in 1899. Yinxu is located in northernmost Henan province near the modern city of Anyang, and near the Hebei and Shanxi province borders. Public access to the site is permitted.
