The Gaehwa Art Park is built on a scale of 50,000 pyeong, including auxiliary facilities located nearby. The Gaehwa Art Park, a large-scale art complex, is home to Herbland, Music Hall, Yukpilsi Park, Birim Park, and Mosan Art Museum in the art park.

The museum's main building, which consists of two floors on an orange roof, is built with precious stones and five stones that are not seen anywhere else in the world and are produced only in Boryeong. Jade stone is a very popular stone in Korea as a tombstone or statue because it has the property of turning blacker as the surface is changed and turning white as it is tightened.

First of all, Herbland, located in the art park, is a new exhibition room this year and is a useful natural learning center for children.
