Taosi

Taosi is an archaeological site in Shanxi, China, notable for its role within the late Longshan culture around 2300 to 1900 BCE. The settlement was surrounded by a significant rammed-clay wall, indicative of a structured society with social stratification. Inside, an internal wall divided the elite residential and ceremonial areas from those of the common populace. Taosi is distinguished by its ancient astronomical observatory, the oldest found in East Asia, which was possibly used for calendrical observations. The site also features a necropolis with highly stratified burials, highlighting social hierarchies. The presence of musical instruments and a painted pole indicates a rich cultural context. Taosi potentially served as a regional center within the Linfen basin, but it did not evolve into a fully developed state, unlike other Central Plains sites.
