In the year 679 AD, during the 19th year of King Munmu's rule, Donggung Palace was built as a venue for state festivals, banquets and as a prince's palace.
According to to History of the Three Kingdoms (Samguksi), that inside the Palace, a pond was dug, artificial hills were created, flowers were planted, and strange animals were brought in and raised. The pond also served as a place to entertain valuable guests and hold banquets for the king and his subjects. The artificial pond with an area of around 190 meters in all four directions was also called the Anapji during at the Joseon dynasty.
Wolji Pond was uncovered during the excavation and dredging work conducted in 1975. The date inscribed on the roof and tiles decorated with stylized floral medallion (posanghwa), confirmed that the original dates of construction were accurate. During the Joseon Dynasty, the pond was neglected and became a straying place for wild ducks and geese hence became Anapji (wild goose and duck pond).
