Overview
Leamaneh Castle is really two buildings in one: a five-storey Gaelic tower house from around 1480, with a four-storey manor added onto its side some 160 years later, all of it now roofless and standing alone in a cattle field. It sits at the junction of the R476 and R480 in the heart of the Burren, about 6.2 km east of Kilfenora, its weathered stone catching the light against the karst pavement behind. You cannot go in – the ruin is on private farmland, closed to the interior – so it’s a roadside photo stop rather than a site to explore. If you’re on a Burren loop drive, give it ten or fifteen minutes from the pull-off and look for the window trick on the manor front (more on that below).
The name and the legend of Red Mary
The Irish name Léim an Eich means “the leap of the horse”. Local tradition says the estate was once offered to anyone who could ride a horse over the castle walls; two challengers fell to their deaths, and a third only cleared them because a charm had been slipped onto the horse’s bridle to keep the land with the O’Briens.
The castle’s lasting association, though, is with Máire Rua Nic Mhathúna – Red Mary. She married Conor O’Brien in 1639, and folklore paints her as fiercely independent and ruthless, with tales of her hanging disobedient servants from the stone corbels. When Royalist fortunes collapsed in the Cromwellian conquest, the story goes that she offered her hand to any Parliamentarian officer who would help secure the estate; she married Cornet John Cooper, a Cromwellian officer, and for a time kept the O’Brien lands out of confiscation. Her reputation for a temper and for hauntings makes the ruin a fixture on Clare’s ghost tours, and it’s reputed to be one of the most haunted castles in Ireland – which is worth knowing if you’re passing near Halloween.
Two building phases
The 15th-century tower house
The original stronghold went up around 1480–1490 for Toirdhealbhach Donn Ó Briain (Turlough Donn O’Brien), then King of Thomond and a descendant of Brian Boru. A classic Gaelic tower house, it was built for survival rather than comfort: five storeys of thick stone walls, narrow arrow slits, a steep spiral stair and cramped, multi-purpose chambers. For generations it was the defensive and administrative heart of the O’Brien estate in north Clare.
The 17th-century manor and the window trick
After his marriage to Red Mary, Conor O’Brien used their combined wealth to turn the fortress into a statement of gentry status. Around 1648, parts of the medieval tower were taken down to make room for a four-storey manor house, its larger mullioned and transomed windows letting more light into the rooms – a clear shift toward domestic comfort.
The builders played a visual trick on the façade: the windows on the upper floors are deliberately narrower and smaller than those below, which exaggerates the building’s height and makes the manor look more imposing from the road. It’s the one detail worth pausing for.
Decline and salvage
The castle’s fortunes fell away in the 18th century and the manor was left to ruin. Over time its best features were dismantled and moved: the ornate barbican-style gate went to Dromoland Castle in the early 1900s, and a stone fireplace now sits in the Old Ground Hotel in Ennis. Today it’s a National Monument (ref. no. 448) in the care of the Office of Public Works, its remaining walls, arrow slits and the faint outline of a former walled garden and deer park left as a record of centuries of upheaval and ambition.
Visiting Leamaneh Castle
Leamaneh Castle is not open to the public. Heritage Ireland and the OPW ask visitors to view the ruin from the roadside only – there’s no access to the interior or the surrounding farmland, and there are often livestock grazing in the field. A small, unmarked dirt pull-off on the R476 fits two or three cars and gives you a safe place to stop for photographs. It fills quickly in summer, so pull in carefully and don’t block the junction.
- Admission: free to view from the road.
- Access: external viewing only; no interior or land access permitted.
- Parking: small pull-off, 2–3 cars; no dedicated car park.
- Facilities: none on site; nearest amenities are in Kilfenora or Corofin.
- Best time: early morning or late afternoon for softer light and fewer passing cars.
Exploring the surrounding Burren
Because it’s a quick stop, Leamaneh works best as one point on a wider Burren itinerary, and the junction makes a natural waypoint on the Burren Way. From here you’re well placed for:
- Poulnabrone Dolmen – a short drive north on the R480, the Burren’s best-known portal tomb, out on the open limestone pavement.
- Aillwee Cave – further north near Ballyvaughan, a show cave with the adjacent Burren Birds of Prey Centre.
- Kilfenora – 6 km west, home to a well-preserved medieval church, high crosses and a couple of traditional pubs.
- Cliffs of Moher – roughly 30 minutes west, easily folded into the same loop.
Take your photos from the pull-off, then use the junction as a jumping-off point for the caves, tombs and coast road that make up the rest of the Burren.
