The palace was divided into two major sections; the Kungsŏng (궁성, 宮城), where the king and royal family resided, and the Hwangsŏng (황성, 皇城), where affairs of state were conducted.

The palace was burned to the ground in 1361 when the Red Turbans invaded and sacked the city of Kaesong, forcing the king to temporarily flee Andong.

Many valuable relics of the late Goryeo period have been uncovered at the site, including ceramics, metal items, ancestral tablets, mirrors, and over 3,000 roofing tiles.

[7] A 25 cm celadon jar with an inlaid monkey and tree design in an underglaze of gold found at the site is held at the National Museum of Korea.

The vase-like object bears an intricate pattern of peonies and vines and used to have holes at the top and bottom; it was speculated to have been a flower pot or a vessel used for some ceremonial purpose.

"[9] In November 2015, the excavation had unearthed a piece of metal type, with initial reports dating it from Goryeo Dynasty, but it requires further study to verify when it was made.
