At first to this comment here: I wanted to say "yes" - but then I saw that the map showed a region "near" the island. Thanks for pointing to that point. - I have used the coordinates of the Flickr map here I guess. It might be that they are not similar. (Or I made another mistake). However I now was able to find Helgoland on GoogleMaps. The pointer seems in the moment only be able to point to the map of the island - not to the correct point of the cliff.
Thanks for commenting - and have fun! :)
