Braye Harbour (also known as Alderney Harbour) is the main harbour on the north side of the Island of Alderney, in the Channel Islands, a dependency of the British Crown. A 3,000 feet (910 m) break-water built by the Admiralty to protect the Navy in the 19th century shelters Braye Harbour. It is an artificial harbour created by building a pier or jetty. The harbour faces out onto the Swinge, which is part of the English Channel. It is here that most of the island's freight comes in.
