The Portugal–Spain border is the international boundary between Portugal and Spain. It is the only border in the world where you can zipline from one to the other, the zipline exists between Sanlucar de Guadiana in Spain and Alcoutim in Portugal. Referred to as "la Raya" in Spanish and "A Raia" in Portuguese, the current demarcation is almost identical to that defined in 1297 by the Treaty of Alcañices. It is one of the oldest borders in the world. The Portugal–Spain border is 1,214 km (754 mi) long and considered the longest uninterrupted border within the European Union. The border is not defined between the Caia river and Ribeira de Cuncos, because of the disputed status of Olivenza, which has been disputed between the two countries for two hundred years.
A microstate existed previously on the border called Couto Misto.
