Forthill, an eminence in Monifieth parish, Forfarshire, ½ mile NW of Broughty Castle. A fort, erected on it in 1548 as a flanking post of the English garrison in Broughty Castle, was dismantled in 1550; left remains 12 feet high till 1782; and is now completely obliterated. A camp was formed on the same eminence fully ¼ mile E of the fort, and has left slight traces of its entrenchments.
