The Rock Garden of Chandigarh has been created by putting together the fossils of ancient life forms found in the Shivalik hills and by recycled waste material. Its creator, Nek Chand, was an inspector in the engineering department. Rock fossils have been arranged into an open air sculpture exhibition. Some of the sculptures include a wall made out of discarded fluorescent tubes, an army of clay monkeys and broken chinaware soldiers and shapes of women made out of discarded glass bangles. The garden covers an area of 6 acres.
