Trim Castle

On the south side of the Boyne, opposite Sheep Gate and south of Yellow Steeple, rises a magnificent stronghold, Trim Castle (National Monument), the largest Anglo-Norman castle in Ireland, covering an area of 3ac/1.2ha. In the center of the castle area, at its highest point, is the square keep, with turrets at the four corners and projecting towers (only three out the original four survive) in the middle of each of the 11ft/3.3m thick walls, giving the massive structure a cruciform plan.

There was a drawbridge operated from the tower on the south side. The outer ward is surrounded by a curtain wall with semi-circular towers (five of which remain) and a moat. The parapet walks originally linked up with the town walls.
