Dundalk and the Gap of the North
During the Nine Years’ War, Dundalk became a base for Mountjoy’s campaigns against Hugh O’Neill’s forces. The wooded Moyry Pass controlled an important route north. Newry and Mourne Museum describes repeated attempts to advance through it in 1600, followed by the construction of Moyry Castle in 1601. Dundalk’s strategic geography was again central to a conflict extending far beyond the town.↗1
The mountain corridor north of Dundalk connects the town’s local history with the final stages of Tudor conquest.
