evidence: The "La Raya" is the international land border shared between Spain and Portugal. With a length of at least 754 miles, the border is the longest of its kind in the European Union. However, the two countries recognize different lengths of the border. Portugal defines the border as being 754 miles in length, while Spain states that the border is 765 miles in length. The difference of 11 miles stems from Olivenza, a region which is claimed both by Portugal and Spain, in a territorial dispute that goes back 200 years. In Portugal, this border is referred to as "The Stripe" (A Raia). Spain has seven provinces found along the border; Ourense, Badajoz, Pontevedra, Zamora, Huelva, Caceres and Salamanca Provinces, while Portugal has ten districts along the border which are Faro, Beja, Evora, Portalegre, Castelo Branco, Guarda, Braganca, Vila Real, Braga, and Viana do Castelo. [...] Olivenza is a region along the Spain-Portugal border whose ownership is disputed by the two countries. According to Spain, the region is part of the country’s Extremadura autonomous community, while Portugal believes the town to be part of its Province of Alto Alentejo. Nonetheless, the administration of Olivenza is done by the Spanish government. The region covers an area of 290 square miles and is home to an estimated population of 11,512 people. Portugal claimed the region since 1297 but had the sovereignty of the town taken by Spain in the aftermath of the 17th century War of Oranges and the signing of the 1801 Treaty of Badajoz.
