The eco-walls made of aluminum cans are one of the most impressing architectures inside the park. These walls are the combination of the concept of environmental protection and modern art. All of these cans are collected from its pre-existing burial ground, Sangjuku Landfill. After being processed by machines, they are finally stacked and built as walls. Upon the surface of these walls, recycled aluminum cans can clearly seen. There are some games designed on the walls, whose purpose is to let children understand the meaning of recycling as well as environmental protection. Meanwhile, these games can let parents and children interact with each other and strengthen parent-child relationship.
