It is situated near the border with Switzerland, 14 kilometres (9 miles) north of Schaffhausen.
Verenahof (also known as Büttenharter Hof or Verenahöfe) was a German exclave in Switzerland, administratively part of the German town of Wiechs am Randen (which is now part of the town of Tengen).
Geographically, it was separated from Wiechs am Randen by a 200–300-metre wide strip of Swiss territory.
By 1964 a treaty was concluded between Germany and Switzerland, which entered into force on 4 October 1967.
The 43-hectare territory, containing three houses and eleven West German citizens, became part of Switzerland.
