ST FLOUR, a town of south-central France, capital of an arrondissement in the department of Cantal, situated at a height of 2900 ft. on a basaltic plateau overlooking the Lander, a tributary of the Truyère, 47 m. E.N.E. of Aurillac by rail. Pop. (1906) 4090. The streets are dark and narrow, but the town has spacious promenades established in the 18th century. St Flour grew up round the tomb of St Florus, the apostle of Auvergne, who died there in the 4th century. The abbey founded there about the beginning of the 11th century became in 1317 an episcopal chapter, and the town is still the seat of a bishopric. The cathedral (1396–1466) is the principal building. The manufacture of coarse woollen fabrics, of earthenware and candles is carried on. A few miles S.E. of the town the gorge of the Truyère is spanned by the fine railway viaduct of Garabit over 600 yds. long and at a height of 400 ft. above the river.
