The Pyrenees, Aquitaine, France
The Pyrenees ,also spelled Pyrénées, is a range of mountains in southwest Europe that forms a natural border between France and Spain. It separates the Iberian Peninsula from the rest of continental Europe, and extends for about 491 km from the Bay of Biscay to the Mediterranean . For the most part, the main crest forms a massive divider between France and Spain, with the tiny country of Andorra sandwiched in between. The Crown of Aragon and the Kingdom of Navarre have historically extended on both sides of the mountain range, with small northern portions now in France and much larger southern parts now in Spain.
