As a result of excavation surveys for four times in order to obtain data for restoration and maintenance of Achasan fortress, various kinds of relics and artifacts were confirmed in three cultural layers including the walls.
Drainage facilities were confirmed on the fortress walls, and hypocaust, waterway and masonry facility were surveyed on the first cultural layer. In the 2nd cultural layer, waterways, masonry facilities and work facilities were confirmed, and catchment site are located in the 3rd cultural layer. Various types of earthenware, tiles, iron and wooden tools were excavated. Among the wooden tools, there are five presumed to be wood tablets. In one, you can see the traces of the letters, but the exact details are unknown. Other inscribed roof-tiles, which can estimate the fortress, and lotus design roof-end tiles corresponding to Goguryeo, were also excavated.
This survey will be a good opportunity to identify the exact nature of the Achasan fortress, along with the archaeological evidence already identified.
