Moyry Pass

The Moyry Pass is a geographical feature on the border between the Republic of Ireland and Northern Ireland. It is a mountain pass running along Slieve Gullion between Newry and Dundalk. It is also known as the Gap of the North.^[1]

The pass was of historical military importance as it controlled the route between Ulster and The Pale around Dublin. Moyry Castle was constructed to guard the pass. A number of battles have been fought in or around the pass, including the Battle of Moyry Pass in 1600 and several engagements during the Williamite War in Ireland.
