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.
[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.
