LO, St, a town of France, the capital of the department of Manche, is situate on the River Vire, 157 miles N.W. from Paris. In the central part of the town, occupying the top of a rocky eminence, is a square containing several of the principal buildings, while several irregular streets diverge from it, and cover the sides of the hill. The only structures of note are,—the Church of St Thomas, now used as a corn-market; the Church of St Croix, an ancient edifice in the early Norman style; and the Cathedral of Notre-Dame, defective and irregular in its architecture, but possessing two imposing towers and finely-painted windows. There are also a museum, a prefecture, a communal college, and a bridge of six arches over the Vire. The square called Champ de Mars is adorned with avenues of trees. Ribbons, linen, lace, druggery, and leather are manufactured; and there are some bleachedfields and dye-works. Cavalry horses and cattle form the staples of trade. St Lo is the seat of tribunals of original jurisdiction and commerce, and of a chamber of manufactures. Pop. (1851) 9156.
