City at Wunushan,
investigation and partial excavation of an area of about 500,000
square meters of the project of the boot-shaped mountain city have
been made. Against a background of mountain cliffs, the city were
guarded by stonewalls along the smooth and gentle curve of the mountain.
The city has three gates, and was divided into two sections, the
part on the mountain and the part at the bottom. On the mountain,
there is a watchtower, water reservoir, and barrack-like groups
of buildings, as well as remains from the late Neolithic, Spring
and Autumn, Warring States, Western and Eastern Han, Wei ,Jin and
Liao periods. About 1,000 pieces of various relics, including pottery
wares, stone, porcelain, bronze and iron articles were unearthed.
After the excavation, the dimension, layout and structure of the
mountain city were verified, and the specialty of construction and
execution method of the construction of the early mountain city
of Koguryo were identified, which provides important evidence that
the mountain city, or Qishenggu City might have been an early capital
of Koguryo. This is a new find in the northeast area.
The Neolithic cultural remains, particularly the discovery of
a group of sites and relics of the early Koguryo period, have provided
new materials for dating the Koguryo culture in the region to an
earlier period, for the establishment of the chronology of the ancient
culture of the Huanren region and the study of its cultural genealogy.
