In 1816, when delimiting their new frontiers, both the Netherlands and Prussia
claimed the calamine-mine of Altenberg (Fr. Vieille Montagne) part of Moresnet (a
municipality of the so-called Land beyond the Meuse of Dalhem).
As no agreement could be reached, the claimed area was "temporarily neutralized"
under a common administration.
In 1830 when Belgium became independent, it replaced the Netherlands as claimant
and administrator.
In 1915, during the German occupation of Belgium, Prussia became sole administrator,
while three years later, after German defeat, it was Belgium that solely governed
the territory.

From 1940 to 1944, during the second German occupation of Belgium, it was briefly
re-annexed to the Prussian Rheinprovinz.
