Concepcion. I. A S. Province Of Chili, bounded E. by the Andes and W. by the Pacific, and having the river Itata on the north and the Biobio on the south; area, about 3,600 sq. m.; pop. 155,382. The soil is fertile and the climate delightful. The cereals and various kinds of fruits are produced in abundance. Among the chief exports are timber, lumber, hides, salted beef, and tallow. Coal of an inferior quality is mined in large quantities. II. The capital of the province, situated on the right bank of the Biobio, 7 1/2 m. from its mouth, and 270 m. S. S. W. of Santiago, in lat. 36° 49' 30" S., lon. 73° 5' 30" W.; pop. about 15,000. It is a well built city, with wide streets crossing at right angles. Near the centre is a square with a fine fountain. Among the principal buildings are a handsome cathedral, a number of churches and free schools, an orphan asylum, a lyceum, theatre, prison, hospitals, and barracks. It is the seat of a bishop. Its port, Talcahuana, about 12 m. distant, on the S. W. side of Concepcion bay, is one of the best in Chili. It has been rebuilt entirely since the earthquake of 1835, and now contains about 5,000 inhabitants, and a number of churches and schools. A railway from Talcahuana to Chilian, 112 m., now constructing, will materially increase its importance.

The bay of Concepcion is shut in by the island of Quiriquina, on each side of which is a good channel, and furnishes an extensive and safe anchorage. - Concepcion was founded by Pedro Valdivia in 1550, on the S. side of the bay. It was burned by the Araucanians several times, and suffered severely from earthquakes. After the earthquake of 1751 it was rebuilt on its present site. In 1823 the Araucanians again destroyed a part of it, and it was nearly ruined by the earthquake of 1835.
