PATHHEAD, a large well-built village of Scotland, in the parishes of Crichton and Cranstoun, in the county of Mid-Lothian, ten miles and a half from Edinburgh. It consists of one long street, built upon both sides of the road leading to Kelso. The houses are generally of one story, and occupied by those engaged in husbandry, in collieries, and in furnishing the district with those necessaries which cannot be easily supplied from the capital. The population is about 1000. The parish church of Crichton is about two miles distant, and was founded in the year 1449. It is a neat little building, of Gothic architecture, in the form of a cross; and the internal arrangement is also Gothic. Near it is the magnificent ruin of Crichton Castle, which, for beauty of architecture, internal accommodation, and strength of walls and situation, is hardly to be excelled by any of the old baronial castles of Scotland.
