Introduction to Dachendun Site

The ruins of Dachendun are now called "Dacheng" by the villagers.

The provincial archaeological team once collected stone axes, copper smelting slag, pottery pats, residual pottery pieces, etc. here. Rice grain agglomerates were also found in the red-burnt soil on the west slope of Dun Dun, which is the earliest discovery in China.

Before the 1980s, the piers and abutments were approximately circular, with three distinct steps from bottom to top. They were made of rammed earth, and the soil was brown, fine, and free of impurities. The topsoil on the back north slope was excavated, and the southeast and west sides are today's cemeteries, which have been basically preserved. The highest remaining floor is 43 meters long and 20 meters wide. The height difference between the first and second floors is 2.5 meters, the slope is steep at an angle of 75 degrees, and the third floor has a gentle slope. After investigation, it was found that except for the serious damage to the topsoil of the site, the lower 4-4.2 meters were well preserved.

The original name of Dachen Dun is "Dacheng Dun". There are two small city piers (commonly known as "Big Beach") 300 meters away in a straight line to the south. The original name of the village in front of the piers is "Huopigang (sound)" , now named "Cangchen", its residents surnamed Chen are descendants of immigrants from De'an, Jiangxi (according to the couplet of the Chen family ancestral hall). Dachendun is a provincial key cultural relic protection unit.
