The Zhenjiang Building ruins at Sanjiangkou in Nanning is in rescue excavation mode now and so far over 300 square meters have been unearthed.
Ten copper coins, black bricks from the building's base and some ceramic pieces for daily use were discovered at the site.
It is thought that people lived here during the Qing Dynasty (1644-1911), which coincides with the historical record that the army were always dispatched to the Zhenjiang Building. The place played an important military strategic role during the Ming (1368-1644) and Qing dynasties.
In addition to the Zhenjiang Building ruins, four sites nearby and over 30 artifacts were also discovered.
As the Zhenjiang Building ruins were facing the threat of collapse and disappearance due to river bank dilapidation and rising water levels, archaeologists conducted a comprehensive survey in 2014 and started the excavation this year.
