This is the Gwangju Folly. Located in Gwangju, South Korea. It was created in 2017 for the purpose of education for children and as a decore. This place is considered a folly because it is a small intervention that is not taken too seriously in the area. It is only 960 m^2. This is to revitalize the urbanization that is occurring in the area.
