The site is located on a hillside within Olympic Park, offering a view of the Mongchon Earthen Fortress. Here, visitors can simultaneously experience the Baekje artifacts of the past and the current state of the Mongchon Earthen Fortress. Taking advantage of the requirement to display a cross-section of the massive earthen fortress, two walls were established within the site. One wall represents the past, displaying Baekje artifacts within the cross-section of the earthen fortress, while the other wall represents the present, showcasing modern life through windows that open toward the supporting facilities. Ultimately, these two walls form an axis extending to the remaining sections of Mongchon Earthen Fortress within Olympic Park, serving as a gateway through time that connects the vast Hanseong Baekje era with the visitors, transcending the boundaries of past and present.
