TheHalligen (German, singularHallig,German:[ˈhalɪç]ⓘ) or thehalliger (Danish, singularhallig) are small islands without protectivedikes.[1] They are variously pluralized in English as the Halligen, Halligs, Hallig islands, or Halligen islands. There are tenGermanhalligen in theNorth Frisian Islands onSchleswig-Holstein'sWadden Sea–North Sea coast in the district ofNordfriesland[2] and one remaining hallig at the west coast ofDenmark (Langli).
The name is cognate to Old-Englishhalh, meaning "slightly raised ground isolated by marsh".[3] The very existence of thehalligen is a result of frequent floods and poor coastal protection. The floods were much more common in the Middle Ages and coastal protection was much poorer.
Thehalligen have areas ranging from 7 to 956 ha, and are often former parts of themainland, separated therefrom bystorm tideerosion. Some are parts of once much bigger islands sundered by the same forces.[4] Some, owing to sediment deposition, have actually grown together to form larger ones.Langeneß (or Langeness) includes a former island by that same name, and two others that were called Nordmarsch and Butwehl.
Dwellings and commercial buildings are built upon metre-high, man-made mounds, calledWarften inGerman orVærft inDanish, to guard against storm tides. Somehalligen also have overflow dikes.[clarification needed]
Not very many people live on thehalligen. Their livelihoods are mainly based ontourism, coastal protection, andagriculture. This last activity mainly involves raisingcattle in the fertile, often flooded,salt meadows.[5][6]
Thehalligen are to be found in theSchleswig-Holsteinisches Wattenmeer National Park. The commercially developedhalligen ofNordstrandischmoor,Gröde,Oland,Langeneß, andHooge are surrounded by the protected area, but not an integral part of it. The smallerhalligen,Habel,Südfall,Süderoog, andNorderoog as well as theHamburger Hallig are parts of the national park. Walks on thetidal flats and informational meetings are offered by tourist boards and the park administration.
In the west the Germanhalligen are protected from the open sea by theNorth Frisian Barrier Island.
Currently, there are 10halligen in Germany. The following list does not include formerly existing Halligen that have either vanished or merged with currenthalligen or the mainland:
On theDanish side, one still exists:
Also DanishMandø used to be a hallig, but it has dikes today. The German peninsula and former island ofGroßer Werder on theBaltic Sea coast is also nicknamed "Baltic Hallig" (Ostsee-Hallig) due to its remote situation and appearance.
An etymology fromCeltic wordhal, meaning "salt" is less likely.
