  Duivelsberg Gelderland, Netherlands | |
Duivelsberg (German: Wylerberg or Teufelsberg, which literally translates to 'the devil's mountain') is a hill and nature reserve in the municipality of Berg en Dal in the Dutch province of Gelderland, near the border with Germany (North Rhine-Westphalia). It is politically significant, however, because Duivelsberg is the only part of the Netherlands that was both annexed from Germany and retained after World War II.
