the capital of a cognominal arrondissement in the department of Ille-et-Vilaine, France, stands on an eminence near the left bank of the Nançon, 24 miles N.E. of Rennes. This was formerly one of the strongest places in Brittany, and frequently figures in history from the eleventh to the fifteenth centuries. It was taken by the English in 1202, and again in 1448. During the last century it suffered from four destructive fires, so that few of its ancient buildings now remain. It is a pleasant town, and has some mineral springs, which attract numerous visitors. Its trade and manufactures are considerable, the former in agricultural and dairy produce, the latter of sail-cloth and hempen fabrics, flannels, hats, leather, &c. Pop. (1851) 8771.
