Overview
Carbad More (Irish: Carbad Mór) is a double court cairn – a notably rare type of Neolithic tomb – situated in a quiet pasture field about 3 km north-west of the coastal village of Killala, County Mayo. Designated as National Monument No 631, the site stands as one of the few surviving examples of its kind in Ireland. The monument consists of two almost-circular courts, each originally opening onto its own segmented burial gallery. The main axis runs roughly north-east to south-west, with the larger court measuring approximately 7.6 m (25 ft) in diameter.
Set against a backdrop of rolling west-Mayo farmland, the tomb is part of a dense archaeological landscape that includes wedge tombs, standing stones, and early medieval ring forts. Its remote, uncommercialised setting makes it a rewarding stop for visitors tracing the deep history of the Irish west coast.
History & Archaeology
The double court cairn dates to the Neolithic period, roughly between 4000 BC and 2500 BC, when farming communities across Ireland were constructing large stone burial monuments to mark territory, honour ancestors, and align with celestial cycles. Archaeologists believe the twin courts at Carbad More began as independent structures that were later joined back-to-back by a shared gallery system – a layout that remains uncommon even among Ireland’s wider court-tomb tradition.
Over millennia, both cairns lost most of their original stone and earth covering. Today, only the stone outlines of the courts and fragmented gallery walls survive above ground. The site was formally recorded by state archaeologists in the 1960s and subsequently placed under State Care. Modern agricultural activity has altered the landscape around the tomb: a farm track now bisects the eastern court, and a second track runs between the two galleries, highlighting the ongoing tension between active farming and monument preservation.
What to See
Approaching the site from the minor road off the R314, you will first notice the western (south-west) court. This is the better-preserved half of the monument. A near-complete arc of stones defines its perimeter, including a cluster of ten uprights forming the portal entrance. Directly opposite the entrance stands a solitary upright stone, widely interpreted as a surviving flank stone that once helped define the court’s ceremonial space.
The eastern (north-east) court is more fragmented. A modern farm track cuts straight through the circular layout, and several original stones have been displaced or buried under centuries of soil buildup. Despite this, the fundamental circular shape remains traceable on the ground, offering a clear sense of the tomb’s original symmetry.
Both burial galleries are now heavily overgrown, which limits detailed inspection but adds to the site’s atmospheric quality. The western gallery retains a clear side-wall structure, though the rear chamber wall has collapsed inward. The eastern gallery shows similar segmentation, with two upright jambs dividing the space into distinct chambers. On the north-west side of each gallery, a pair of perpendicular stones may represent surviving buttress stones that once supported the cairn’s weight.
Getting There & Parking
By car – From Killala, follow the R314 north for approximately 2 km. Turn left onto the minor road that leads to a farm gate marked by a simple metal post. From the gate, a short grass track (around 200 m) leads directly to the tomb. The gate is typically unlocked during daylight hours.
Parking – Free parking is available in Killala village near the harbour, or at a small roadside lay-by opposite the farm gate. The lay-by is a basic gravel space with no facilities, bins, or toilets on site.
Public transport – The nearest bus stop is in Killala town centre. From there, you will need to arrange a local taxi or walk the 3 km to the site, as no regular public transport serves the immediate area.
Visiting Tips
- Footwear: Sturdy boots or walking shoes are essential. The ground is uneven, and the gallery entrances are often muddy or slick with grass.
- Navigation: Mobile signal can be patchy once you turn off the R314. Load the GPS coordinates (54.236656 N, 9.256804 W) into your phone beforehand, or bring a printed Ordnance Survey map (sheet 24).
- Best time to visit: Summer months bring thick brambles and nettles into the galleries. Early spring or late autumn usually offers clearer sightlines and quieter conditions.
- Livestock: The field is working farmland. Keep dogs on a short lead at all times and be aware of grazing cattle or sheep.
- Site etiquette: There is no formal signage, but the monument is legally protected. Stay on the established grass track, do not lean on or move any stones, and take all waste with you.
Further Exploration
Carbad More sits within a remarkably rich prehistoric corridor. If you have a few hours, you can easily combine it with nearby sites:
- Rathfranpark Wedge Tomb (0.6 km south-west) – A well-preserved passage tomb with a distinct wedge-shaped chamber.
- Breastagh Ogham Stone (5 km south-west) – A Bronze Age standing stone later carved with early medieval Ogham script.
- Céide Fields (15 km north-west) – The world’s oldest known field system, preserved under peat and managed by the National Park Service.
- Kilcummin (1.6 km north-west) – A historic parish town with marked coastal walking routes and traditional pubs.
These locations form a logical half-day loop that showcases the depth of Mayo’s archaeological heritage. Start in Killala for breakfast and parking, follow the minor roads north, and allow plenty of time for careful navigation. Download your route before setting out, as the final approach to Carbad More is unpaved and best tackled slowly.
