Büsingen am Hochrhein

Büsingen am Hochrhein (German:, lit. 'Büsingen on the Upper Rhine'; Alemannic: Büesinge am Hochrhi, pronounced, often known simply as Büsingen, is a German municipality in the south of Baden-Württemberg and an enclave entirely surrounded by the Swiss cantons of Schaffhausen, Zürich and Thurgau. It has a population of about 1,450 inhabitants. Since the early 19th century, the village has been separated from the rest of Germany proper by a narrow strip of land containing the Swiss village of Dörflingen. The distance to this enclave is approximately 5 km from the town of Schaffhausen and 3 km from Dörflingen, the nearest village.

Politically Büsingen is part of Germany, forming part of the district of Konstanz, but economically it forms part of the Swiss customs union, along with the principality of Liechtenstein and up until 2019, albeit unofficially, the Italian village of Campione d'Italia.
