Overview
In 1595 Hugh O’Neill’s men caught an English army under Sir Henry Bagenal in the drumlins around Clontibret and cut it to pieces – the opening battle of the Nine Years’ War, and the first hard evidence that Ulster’s Gaelic lords could beat the Crown in the field. A stone plaque on the N2 is about all that marks it now. The village itself is tiny: 172 people at the 2016 census, a church, a shop or two, and a GAA club, Clontibret O’Neills, founded in 1913 and still carrying the victor’s name. It sits a few kilometres from the border, midway between Monaghan town and Castleblayney on the N2.
Come for the history and the walking, not for the village – there’s no restaurant, and the honest advice is to eat in Monaghan or Castleblayney and treat Clontibret as a trailhead.
The 1595 battle, and what came after
The fighting followed the execution of local MacMahon leaders by the English in 1591, which pushed the district into open revolt. O’Neill’s victory here in 1595 set the tone for a war that would run to 1603 and remake Ulster. The plaque on the N2 just outside the village is quiet about all of that; if you want the fuller story, the County Monaghan museums fill it in.
Clontibret made the news again in August 1986. Protesting the Anglo-Irish Agreement, the unionist politician Peter Robinson led a crowd across the border into the village square before the gardaí turned them back – the “Clontibret invasion”, a small, tense reminder of where the line runs.
And there may be gold under the fields. Since a 2008 discovery, the mineral company Conroy Gold has estimated more than a million ounces along the Orlock Bridge trend, in ground once worked for antimony at the old Tullybuck mine. Whether any of it is ever dug up is another question. The parish has produced its share of names too, among them the Fenian general John O’Neill – who went on to lead raids into Canada and found an Irish colony in Nebraska – and the classical historian J. B. Bury.
The Wildlife and Heritage Centre (closed)
For years the village’s main draw was an unusual one. At Listinny, former Wildlife Service ranger Peadar Morgan built a heritage centre around a collection he’d gathered over 23 years in the field: more than 300 birds and mammals, casualties he’d had professionally taxidermied, each shown with the story of how it came to him, alongside an archive of Irish heritage pieces. Morgan died in 2019 and the centre closed with him. It’s worth knowing before you go looking – the collection is no longer open to the public.
Walking the Monaghan Way
Clontibret sits on the Monaghan Way, a long-distance route that stitches together stretches of a disused Great Northern Railway line and quiet back roads, waymarked with yellow arrows on black.
- Stage 1a (about 15 km, 3–4 hours): Monaghan town to Clontibret, through Castleshane Demesne and across the 1595 battlefield. Mostly paved or good gravel, gently rolling.
- Stage 2 (about 19 km, 4 hours): Clontibret south to Castleblayney over farmland, with distant views to the Mullyash hills. A shorter first section (about 8 km) reaches the Mullyash foothills in a couple of hours.
- Explore Clontibret Loop (6.56 km, about 1 hour 20): a paved circuit on quiet roads through Tullycorbet, fine for cyclists and dog-friendly.
If you’ve a dog, note the official Monaghan Way discourages them, but the local roads and the Clontibret Loop are grand. Bring a waterproof either way – Monaghan weather turns fast.
Churches
The Catholic parish keeps three churches across the area: St Mary’s north of the village, St Michael’s in Annyalla and All Saints in Doohamlet. In the village, St Colman’s Church of Ireland stands on an early Christian site with roots in the monastic period.
Getting there and practical tips
- By car: Clontibret is on the N2 between Monaghan town (about 10 km north) and Castleblayney (about 15 km south); from Dublin, follow the N2 north. There’s roadside parking near the centre.
- By bus: Bus Éireann routes 162 and 182 stop at Carrickaderry, linking Clontibret to Monaghan, Dundalk, Clones and Cavan.
- Food and beds: shops for the basics only; for a meal or a room, head to Monaghan or Castleblayney, or the B&Bs around Ballybay.
Nearby
- Rossmore Forest Park – woodland trails and a lake near Monaghan town, good for families and dogs.
- Inniskeen Round Tower – an early medieval round tower about 30 km southeast, in the village Patrick Kavanagh made famous.
- Dartrey Estate – a wooded former demesne for a longer walk or drive.

Do the first leg of the Monaghan Way from Monaghan town and you’ll cross the 1595 battlefield on your way in – the best way to see why anyone still remembers Clontibret at all.
