Büsingen am Hochrhein ("Buesingen on the Upper Rhine"), commonly known as Büsingen, is a German town entirely surrounded by the Swiss canton of Schaffhausen and, south across the Rhine, by the Swiss cantons of Zürich and Thurgau. It has a population of about 1,450 inhabitants. Since the early 19th century, the town has been separated from the rest of Germany by a narrow strip of land (at its narrowest, about 700 m wide) containing the Swiss village of Dörflingen.
Administratively, Büsingen is part of Germany, forming part of the district of Konstanz, in the Bundesland of Baden-Württemberg, but economically, it forms part of the Swiss customs area, as do the independent principality of Liechtenstein and the Italian town of Campione d'Italia. There are no border controls between Switzerland and Büsingen or the rest of Germany since Switzerland joined the Schengen Area in 2008/09.
Büsingen is highly regarded as a holiday destination in summer by both German and Swiss visitors from around the area for its recreational areas along the Rhine. The town is also the home of the European Nazarene College, a relatively large and internationally-orientated Bible college.
