Helgoland or Heligoland, (as readers of English more usually know it), was formerly known as Heyleigeland or ‘Holy Land’, is an island situated in the North Sea off the coast of Germany with a smaller uninhabited island (Sand Island) to the east. They were a British possession from 1807 until 1890.
Jürgen Spanuth suddenly alerted the world of Atlantology to its possible significance in the 1970’s when he published a book that claimed it as the location of Plato’s Atlantis. Interestingly, the controversial Oera Linda Book was allegedly written on the nearby Frisian Islands in the Frisian language.
Helgoland today is only a fraction of its size twelve hundred years ago(a). There is a tradition that it was once joined to the German mainland. It was also an important source of copper in Northern Europe. (In the map above, Helgoland is the two small islands in the shaded area). It has also been described as formerly the highest point in Doggerland.
Helgoland is also home to something found nowhere else on the planet, namely, red silex or flint, apparently highly prized during the Neolithic, Bronze and Iron Ages(c).
