Alta Cerdanya

42°30′N1°58′E / 42.500°N 1.967°E / 42.500; 1.967French Cerdagne, also known as Upper Cerdanya (French: Haute-Cerdagne, IPA:; Catalan: Alta Cerdanya, IPA:; Occitan: Alta Cerdanha), is the northern half of Cerdanya, which came under French control as a result of the Treaty of the Pyrenees in 1659, while the southern half remained in Spain (as a part of Catalonia). It is the only French territory on the Iberian Peninsula, as it is located on the south side of the Pyrenees Range between France and Spain. For example, the Segre river, which goes west and then south to meet the Ebro, has its source in the French Cerdagne. An inadvertent result of the Treaty of the Pyrenees is the Spanish municipality of Llívia, which is an exclave completely surrounded by French Cerdagne.
