Kurkku Fields, Japan
Tucked into a corner of Kurkku Fields sits a library built inside the earth. The fields were previously home to flat, dry land and construction debris. As the lush valley was restored, the architects believed the building should sit beneath the plants and microorganisms in the soil, allowing the cultivated soil layer to remain undisturbed. This idea led to the creation of the library, a "small cleft in the earth" where farmers could stop to rest.
