The territorial waters (12 mile zone) of the two countries meet exclusively along the Øresund, extending to about 115 kilometres (71 mi), approximately between Höganäs and Falsterbo.
Until 1658, the historic provinces of Scania, Blekinge and Bohuslän (and until 1645 also Halland) belonged to Denmark, so that the Denmark–Sweden border ran across what is now southern Sweden.
There was no land border with Denmark before July 2000 when the Øresund Bridge was opened, which had relaxed customs checks from the start.
In May 2017 the European Commission decided that this type of carrier's responsibility is not legal in the EU so they were abandoned, but the border control for arrivals on the Swedish side remained.
