Aragon is one of the 17 autonomous communities of Spain. Located in the country's north, it stretches from the imposing Pyrenees mountains south to the expansive central Iberian plateau. To the east of Aragon lies Catalonia, while La Rioja, Castilla y Leon and Navarra are its neighbors to the west.

Aragon encompasses the eastward-flowing Ebro River and its vast valley, the river being one of the largest and most important in Spain. The waterway also divides Aragon's wine regions, with Somontano occupying the north and three smaller regions located further south.
