What you'll actually see

The tower is small, square and three storeys high, with distinctive rounded corners that set it apart from most Irish tower houses. Look for the dense scatter of gun-loops across the walls and the machicolation slot above the doorway, both signs this was a working military post, not a home. Inside there were no stairs at all, the floors reached by ladder, which is why you view it from the outside today. One isolated stretch of the old bawn wall still stands to the south-east, the rest long gone.

Good to know before you go:

Moyry Castle is an unstaffed open monument and does not run its own programme, but the wider Ring of Gullion and Newry, Mourne and Down area host living-history days, heritage walks and guided tours through the year. It is worth checking what is on locally before you travel.

The story

The story of Moyry Castle

Moyry Castle was built in June 1601 by Charles Blount, Lord Mountjoy, the English Lord Deputy of Ireland, during the closing years of the Nine Years' War against Hugh O'Neill, Earl of Tyrone. The pass it guards, the Gap of the North, was the key route between Ulster and Leinster, and whoever held it controlled movement in and out of O'Neill's heartland.

The year before, in autumn 1600, Mountjoy's army of around 3,000 foot and 300 horse had tried to force the pass against O'Neill's troops, who had fortified it with trenches and earthworks. The fighting over several days in late September and early October was bloody and inconclusive. To finally secure the ground, Mountjoy ordered a stone keep raised in the pass, and it was completed in roughly a month in 1601.

A Captain Anthony Smith was made constable and left to hold the castle with twelve men. The tower had a short military life but saw use again in the 1641 rising, and the pass below carried King William's army north in 1690 during the Williamite War. The squat tower with its rounded corners, gun-loops and machicolation was always a soldier's building rather than a residence, which is why it has no internal stair.

The castle was taken into state guardianship in the twentieth century, with preservation records noting it as early as 1932. Today it stands in the townland of Carrickbroad as a State Care Historic Monument, cared for by the Department for Communities, with one stretch of its bawn wall surviving beside the roofless tower.
