Hallhill, an estate, with a mansion, in Glassford parish, Lanarkshire, 2 miles NE of Strathaven. An ancient baronial fortalice, near the site of the mansion, contained an arch so spacious that a hundred men could be arrayed beneath it; but, falling into ruin, was taken down about 1828, and then was found to contain fragments of very beautiful china, with other relics.
