thumb Langstone Harbour is an inlet of the English Channel in Hampshire, sandwiched between Portsea Island to the south and west, Hayling Island to the south and east, and Langstone to the north. Geographically it is a ria. Together with Chichester Harbour, which is at the other (eastern) side of Hayling Island it is designated as a Special Protection Area for wildlife. West of Portsmouth is Portsmouth Harbour and the three linked harbours are important recreational and conservation areas as well as supporting commercial fishing and shipping. It is administered by the Langstone Harbour Board.〔(Harbour Board )〕 The eastern boundary with Chichester Harbour is defined by a historic causeway known as the wade way, which was originally the only crossing between Hayling Island and the mainland. It is now impassable, having been cut in two by a deep channel for the Portsmouth and Arundel Canal in the 1820s (for further information see Langstone). ==Islands== Langstone Harbour contains a number of islands; Baker's Island (), North Binness Island (), South Binness Island () and Long Island (). These are subject to erosion and during the 1990s a seven-year archaeology project took place〔(Summary of archaeology )〕 before their history was lost to the seas. There are also two smaller islands. Round nap island which is connected to South Binness Island by a tidal causeway and Oyster Island. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Langstone Harbour」の詳細全文を読む スポンサード リンク
