a burgh of barony of Scotland, partly in the county of Perth and partly in that of Forfar. It stands on the Isla, a small tributary of the Tay, about 13 miles N.E. from Perth, and 61 miles by railway from Edinburgh. The town is well-built, and, in addition to the parish church, contains chapels for the Free Church, United Presbyterians, Episcopalians, Original Seceders, and Independents. Its trade consists in the weaving and bleaching of linen, and the tanning of leather. In ancient times it was famous for a Cistercian abbey, founded on the site of a Roman camp by Malcolm IV. in 1164. This building, however, was destroyed at the Reformation, and only a few ruins now remain. Pop. (1831) 2004.
