Sark is a part of the Channel Islands in the southwestern English Channel, off the coast of Normandy, France. It is a royal fief, which forms part of the Bailiwick of Guernsey, with its own set of laws based on Norman law and its own parliament. It has a population of about 500. Sark has an area of 2.10 square miles. Little Sark is a peninsula joined by a natural but high and very narrow isthmus to the rest of Sark.
Sark is one of the few remaining places in the world where cars are banned from roads and only tractors and horse-drawn vehicles are allowed. In 2011, Sark was designated as a Dark Sky Community and the first Dark Sky Island in the world.
