Overview
Slieve na Calliagh (Irish: Sliabh na Caillí, “mountain of the hag”) rises to 276 m south‑east of Oldcastle in County Meath, making it the county’s highest point. The ridge – often called the Loughcrew Megalithic Hills – is a cluster of four peaks (Carnbane East, Carnbane West, Carrickbrack and Patrickstown) dotted with more than thirty Neolithic passage‑tombs. The landscape is steeped in folklore: the Cailleach, a giant hag, is said to have dropped stones from her apron, forming the cairns that dominate the skyline. Today the site is a protected National Monument and one of Ireland’s four great Neolithic cemetery complexes.
History / Background
The monuments date to c.3400–3000 BC, placing Loughcrew among the earliest monumental burial sites in Ireland. Two principal cairns – Cairn L and Cairn T (the “Hag’s Cairn”) – were erected around 3200 BC and are renowned for their rare megalithic art of spirals, lozenges and solar motifs. 19th‑century antiquarian E.A. Conwell first recorded the stones, followed by surveys from Rotherham (1895) and George Coffey (early 1900s). Modern research by Martin Brennan (1980) demonstrated that Cairn T is aligned to capture the sunrise on both the spring and autumn equinoxes, illuminating a decorated back‑stone in a spectacular light display. The name Sliabh na Caillí – “Hill of the Witch” – reflects a later legend of a witch who dropped an apron of stones across the ridge.
What to See & Do
- Cairn T (The Hag’s Cairn) – The highlight of the complex. Its narrow passage leads to a chamber whose back‑stone bears intricate carvings that glow when the equinox sun streams down the passage. Visits in March and September allow travellers to witness this natural light show.
- Cairn L and surrounding mounds – Smaller tombs, many still capped with white quartz, echo the brilliance of Newgrange and provide intimate close‑up views of Neolithic architecture.
- Carnbane West Summit – Although the cairns on this peak are on private land and cannot be entered, the hill‑walk offers a panoramic vista of the entire Loughcrew landscape, the River Boyne, the Hill of Tara and, on clear days, the Wicklow Mountains, Mourne range, Slieve Gullion and the distant coastline.
- Megalithic Art – Kerbstones on Carnbane West and the exposed stones at Cairn T display faint spirals, lozenges and cup marks, hinting at the symbolic language of the builders.
- Birdwatching & Wildlife – The upland grassland supports skylarks, meadow pipits and occasional red‑kites soaring above the ridge.
- Photography – Sunrise and sunset cast long shadows across the stones, making the site ideal for dramatic landscape shots.
- Loughcrew Megalithic Centre & Gardens – Situated at the foot of the hills, the centre offers guided tours, interactive displays of Neolithic tools, a café, a shop, and a Fairy Trail through gardens that delights children.
- Family‑Friendly Walk – A short 20‑30 minute loop marked with posts circles the summit, includes seating at two viewpoints, and is suitable for strollers and young children.
Getting There & Parking
The site is accessed via the R158 road from Oldcastle. A well‑signed turn‑off leads to the Loughcrew Megalithic Centre where a small car park is provided for visitors. Parking is limited, especially in the summer months, so arriving early is advisable. The private Carnbane West side has no public parking; the only official parking is at the centre.
