Biella is a town and comune in the northern Italian region of Piemonte, the capital of the province of the same name, with some 45,800 inhabitants as of 2009. It is located about 80 km northeast of Turin and about 80 km west-northwest of Milan.
It lies in the foothills of the Alps, in the Bo mountain range near Mt. Mucrone and Camino, an area rich in springs and lakes, the heart of the Biellese Alps irrigated by several mountain torrents: the Elvo to the west of the town, the Oropa and the Cervo to the east. Nearby natural and notable tourist attractions include the outlook at Zegna with the ski resort of Bielmonte; Burcina Natural Reserve; and the moors to the south of town. The Sanctuary of Oropa is a site of religious pilgrimages. In 2003, the Sacred Mountain of Oropa was inserted by UNESCO in the World Heritage List.
Biella is an important wool processing and textile centre. There is a small airport in the nearby comune of Cerrione.
