Aburrá Valley (in Spanish
Valle de Aburrá), is the natural basin of the
Medellín River and one of the most populous valleys of
Colombia in its
Andean Region with near 4 million inhabitants in its biggest urban agglomeration:
The Metropolitan Area of the Aburrá Valley. The valley is located on the
Central Range, over the
Antioquian Mountain just between the Magdalena and
Cauca valleys from east to west. The name "
Aburrá" comes from an ancient language spoken in the place by the "
Aburreans" (Aburraes) before the Spaniards settled the place during the 16th century.
