Enkarterri

Enkarterri is a comarca of the province of Biscay, in the Basque [Country (autonomous community)|Basque Country], Spain. It is one of the seven eskualdeak/comarcas or districts that make up the province of Biscay. Its administrative centre is Balmaseda.

Nowadays the name usually refers only to the rural western part of the historical territory, while the eastern urban area is known as the Left Bank and is part of the Greater Bilbao comarca.
