Germany’s tiny geographic oddity bbc.com

Surrounded by Switzerland, but owned by Germany, the tiny enclave of Büsingen am Hochrhein has managed a binational existence for centuries.
On 1 August, Switzerland’s National Day, summer holidaymakers are out in force. Flotillas of rafts and canoes bob along the Rhine River, sunbathers layout on the grassy shore, and on the largely empty streets an occasional public bus rumbles by, decorated for the festivities with Switzerland’s familiar red flag with a white cross.

It’s a perfect holiday scene, except for one nagging detail. All this merrymaking marking the anniversary of Switzerland’s confederation is taking place in Germany.
