Quinto Real (French: Pays Quint, Basque: Kintoa) is a Spanish territory with exclusive rights of use by France on the border between the two countries, in the Pyrenees mountains, in northeastern Navarre.
Since the migration of cadets, deprived of any right to heirship by primogeniture, in this desert place, and the division of Navarre into Spanish and French parts, this area was the object of disputes between French shepherds from Saint-Étienne-de-Baïgorry and Spanish shepherds from Erro, and several measures which aimed to reduce these conflicts failed, such as a royal order on 1614 and the 1659 Treaty of the Pyrenees.
[2] The area is part of Spain but is administered by France; the inhabitants are French citizens by default but have the right to dual citizenship.
[8] The Guardia Civil maintain order while utilities are furnished by France: La Poste distributes the mail and EDF electricity.
[2] Each May, cattle going to the Quinto Real are marked with a special symbol and their owners have to pay €71 per head (2011 costs) to the Erro valley.
