Frisian Islands
The difference between historical-political and geographical view of East Frisia has left the island of Wangerooge with an "ambiguous" situation. On the one hand it is counted geographically as one of the East Frisian Islands. On the other hand, it has belonged, politically and historically, to Jever Land for centuries and hence, since 1818, to Oldenburg, and today to the district of Friesland. It is in a sense the only part of "Oldenburg" in the (inhabited) East Frisian Islands.
