Originally built in 1305 by Domnall O'Neill on Castle Hill, one of the area's highest points, Dungannon Castle was later rebuilt as a mansion house by Thomas Knox, 1st Earl of Ranfurly. Only two ruined towers survive today; the site underwent archaeological excavation, including a Channel 4 'Time Team' dig in 2007 that uncovered sections of the original moat and walls.
