Olivenza

Olivenza or Olivença is a town located in southwestern Spain, near the Portuguese border, on a historically disputed section of the Portugal–Spain border. Its territory is administered by Spain as a municipality belonging to the province of Badajoz, and to the wider autonomous community of Extremadura.

The town of Olivença was under Portuguese sovereignty almost continuously between 1297 and 1801, when it was occupied by Spain during the War of the Oranges and ceded that year under the Treaty of Badajoz. Spain has since administered the territory, whilst Portugal invokes the self-revocation of the Treaty of Badajoz, plus the Treaty of Vienna of 1815, to claim the return of the territory. In spite of the territorial dispute between Portugal and Spain, the issue has not been a sensitive matter in the relations between these two countries.Olivenza and other neighbouring Spanish and Portuguese towns reached an agreement in 2008 to create a euroregion.
