Yangsan Museum opened April 11, 2013 to preserve and study excavated cultural items from the Yangsan area, as well to act as an educational and cultural content space.

The design of the museum resembles the dolmen in Singi-dong and curved lines seen on the eaves of Tongdosa Temple’s Daeungjeon Hall, while the rotunda in the middle of the museum visualizes the old fire beacon on Wonjeoksan Mountain.

Yangsan Museum is comprised of five floors presenting the history and culture of Yangsan. The main exhibition hall is divided into a History Hall, Ancient Hall, Children's Historical Experience Hall, Special Exhibition Hall, and 3D Visual Hall. As the exhibition halls are divided by theme and period, the flow of the museum allows you to easily absorb the information on display. Not only does the museum display relics, but also models, dioramas and a variety of footage is on display, presenting the past, present, and future crossing over in one space to give visitors a nice sense of realism as they tour the facility.
