a town of Spain, province of Seville, at the entrance of a valley, not far from the Salado, 40 miles E.S.E. of Seville. It is built in a semicircular form on the slope of a hill, and has broad regular streets, well paved, and adorned with numerous fountains, which are supplied with water brought from the distance of one mile by an underground channel. On the top of a hill stands a castle, which commands an extensive view of the fertile country in the vicinity of the town. The collegiate church is a building in the mixed Gothic and Cinquecento styles, and contains several fine pictures by Ribera. The church having been occupied as a fortress by Marshal Soult, these, as well as the sculptures over the portal, have been much defaced by his soldiery, and a large quantity of ancient plate was carried off. The vaults, which are supported by Moorish arches, contain the tombs of the Giron family, by one of whom the church was founded in 1534. The university, which formerly existed at Osuna, was suppressed in 1824; but there is still a college, which is a stately building with a large quadrangle. There are, besides, numerous elementary schools, and several hospitals. In the environs of Osuna, there are many hermitages and public walks. A great number of the inhabitants are engaged in agriculture; but there are also numerous manufactories of iron, earthenware, bricks, oil, hats, linen, &c. Many mats are also made from Spanish broom; and this sort of work employs a large number of the poorer people. Wheat, barley, and beans are exported in large quantities to Seville and Malaga.
