The theme park that is to be created inside the Let’s Run Park Seoul Horse Racing Track is carried out with a concept of ‘Dioramic Island’, with the purpose of actualizing a dioramic landscape from an epic landscape. Diorama refers to making a scene by installing a model on the background, and the theme park is proposed to be made as a new theme park that expresses the change of Mounds & Sunkens and make a third space that is in between imagination and reality. The theme park will become a place where there are events and festivals with special pavilions and sensational programs and with themed landscapes full of imagination all year round. It will also be created as a family park full of experiences related to horses for the children and full of enjoyable activities for the whole family.
