The name Anapji appears in the 16th century Joseon era document Augmented Survey of the Geography of Korea (동국여지승람; 東國輿地勝覽)[1] with the explanation that King Munmu made the pond with Taoist aesthetics.

[citation needed] As part of the renovation project of historic sites in Gyeongju, Anapji was dredged and rebuilt in 1974.

An abundance of unique and extraordinarily designed roof tiles, architectural materials, pottery, gilt bronze figures of Buddha, jewelry, accessories and other everyday items were discovered, offering an insight to Buddhist art and everyday life in Silla.

Approximately 730 relics are on display at the Anapji Exhibition Hall, the special gallery of the Gyeongju National Museum.

The site of Imhaejeon is also a part of the grounds, the most important building on the property and the structure used as the crown prince's palace.
