It is well evidenced by the historical sites and relics preserved in their original state in Kaesong City of the DPRK, the then capital of Koryo Kingdom (918-1392).

Typical are decorative sculptures at the mausoleum of King Kyonghyo, situated at the foot of Mt Pongmyong in Haeson-ri of the city, which show the medieval stone sculpture.

Among them are symbolic animals embossed in twelve-fold stone screen, stone handrail, stone stairs, stone post, stone altar, stone lantern and stone sheep and stone tigers around the mausoleum. In particular, two granite-stone figures depicting a military officer and a civil official are estimated as the best of the old stone sculptures kept in the country until now.

At the Ryongthong Temple in Ryonghung-dong of the city, there is also a monument called Taegakguksabi, which is propped by a stone turtle. Engraved on the front and back sides of the monument are patterns of phoenix and flower.

The Hyonhwa Temple's seven-storied pagoda at the Koryo Museum is big in size and grand in shape and a lot of Buddhist figures carved in each storey of the pagoda are exquisite and lifelike.

Besides, there are a dragon head sculpture at Manwoldae royal palace site, a stone lantern at the Kaeguk Temple, a five-storied pagoda at the Pulil Temple, a pagoda at the Hungguk Temple and other relics showing the Korean nation's excellent stone sculpture.
