Sark (Sercquiais: Sèr or Cerq, French: Sercq) is an island in the southwestern English Channel, off the coast of Normandy, and part of the archipelago of the Channel Islands. It is part of the Bailiwick of Guernsey, a self-governing British Crown Dependency, with its own set of laws based on Norman law, and its own parliament. It was a royal fiefdom until 2008, when the Constitution of Sark went into effect.
Sark has a population of about 500. Including the nearby island of Brecqhou, it has an area of 2.10 square miles (5.44 km). Little Sark is a peninsula joined by a natural but high and very narrow isthmus to the rest of Sark Island.
