Northumberland International Dark Sky Park is the largest area of protected night sky in Europe, covering 572 square miles (1,483 square kilometres). The area was awarded gold status designation in 2013 by the International Dark Sky Association in Tucson, Arizona, the world authority on light pollution. This status means that controls are now in place to prevent light pollution and to protect the night sky.
