provincia (province) in the comunidad autonoma (autonomous community) of Castile-Leon, north-central Spain. It was formed from part of the historic region of Old Castile in 1833. The terrain is varied: to the north are the Moncayo and Urbion mountain ranges; in the centre, around Soria city, the provincial capital, is a flat plain watered by the Duero River; and in the south, this same plain gives way to rolling hills. Barley, wheat, and rye are grown in areas irrigated by the Duero, and lumbering (pine), sheep grazing, and pig raising also are carried on in the province. Food processing and services, the province's dominant economic activities, are concentrated in the provincial capital. Area 3,979 square miles (10,306 square km). Pop. (2007 est.) 93,593.
