Anapji, or Anap Pond is an artificial pond in Gyeongju National Park, South Korea. It was part of the palace complex of ancient Silla (57 BCE - 935 CE). It was constructed by order of King Munmu in 674 CE. The pond is situated at the northeast edge of the Banwolseong palace site, in central Gyeongju. It contains three small islands.
After the fall of Silla, the pond fell into disrepair for many centuries. The Donghae Nambu Line railroad was constructed along the edge of the pond in the early 20th century. The pond was dredged and re-built in 1974, as part of a general program of restoration and excavation of Gyeongju-area relics. A large number of relics were retrieved from the pond, many of which are now exhibited in a special gallery of the Gyeongju National Museum.
Anapji was originally located near the palace of Silla called Banwolseong. According to Samguk Sagi which contains a large material about ancient history of Korea, "During the era of the King Munmu new pond was made in the palace and grew flowers and birds within this pond.". It refers to large development of Silla dynasty after it unified three kingdoms. Now Anapji is allotted in Inwang-dong, Gyeongju.
