Lennox Castle, a very strong ancient fortalice in Currie parish, Edinburghshire, on a rising-ground on the right bank of the Water of Leith, ¾ mile SW of Currie village. It commanded a charming view down the vale of the Water of Leith towards the Firth of Forth; had a subterranean communication with another building on the opposite bank of the river; belonged to the Earls of Lennox; was an occasional residence of Queen Mary and the Regent Morton, and a favourite hunting-seat of James VI., from whom it passed into the possession of the celebrated George Heriot; and, having fallen into decay, it became an utter ruin, now popularly known as Lymphoy.—Ord. Sur., sh. 32,
