A police building opened in China, which is built entirely in a cave, ChinaDaily reports.
It took architect Li Shengshou and his colleagues 17 years to build a unique police station in Gansu Province, Yadan National Geological Park. The police station is entirely out of the rock.
Construction began in March 2001, when care for the development of the national park began. The park covers 400 square kilometers and is also called the "Devil City" because visitors can hear the sound of the whistling of the constant wind.
