 In January 2011, the International Dark-Sky Association designated Sark as Europe's first Dark Sky Community and the first Dark Sky Island in the world.This designation recognises that Sark is sufficiently clear of light pollution to allow naked-eye astronomy.Although Sark was aided in its achievement by its location, its historic ban on cars and the fact that there is no public lighting, it was also necessary for local residents to make adjustments, such as re-siting lights, to cut the light pollution.
