Rathcoran – Neolithic Passage Tomb and Bronze Age Hillfort

📍 Baltinglass Hill, Wicklow

🏛️ Attraction

Last updated: 28 April 2026

Overview

Rathcoran crowns the summit of Baltinglass Hill (also known as Tuckmill Hill) at an altitude of about 370 m. The site is a striking blend of two very different prehistoric phases: a Neolithic passage tomb built around 3500‑3000 BC and a later Bronze Age hillfort, dated to roughly 1000 BC, that encloses the cairn within a double stone‑earth rampart. From the top you can see the River Slaney winding through the Wicklow countryside, making Rathcoran one of the most photographed high‑points in south‑west Wicklow.

History

Neolithic passage tomb

The tomb at Rathcoran belongs to the same generation as the famous Boyne Valley monuments. Excavated by P. T. Walshe between 1934 and 1936, the burial chamber revealed the cremated remains of at least three adults and a child. Among the finds were flint scrapers, Carrowkeel‑type pottery, bone pins and a stone axe. Carbonised hazelnuts, wheat grains and a saddle quern point to a community that cultivated crops at unusually high elevations for the period. Fragments of quartz suggest that the builders may have used the stone for decorative purposes, perhaps to catch the light on the cairn’s surface.

Bronze Age hillfort

Around a millennium later, a bivallate ringfort was erected around the cairn, giving Rathcoran its modern name – from the Irish Ráth Cuaráin or possibly Ráth Charnáin (“ringfort of the cairn”). The hillfort’s double rampart follows the natural contour of the hill, reaching up to 16 m in width and nearly 3 m in height on the northern and north‑western sides. Archaeologists such as Condit (1992, 1998) and Waddell (1998) argue that the fort was never fully completed; quarry pits and unfinished banks hint at a sudden abandonment of the project.

Modern LiDAR, GPS and geophysical surveys (O’Driscoll 2012‑2014) have identified up to fifty circular hut platforms inside the enclosure, evidence of substantial Iron Age occupation. The interior is now cloaked in dense gorse and scrub, adding an air of mystery to the ancient stronghold.

What to See & Do

  • Passage tomb chambers – The main north‑side chamber measures about 1.2 m in diameter and contains three shallow recesses and a stone basin with a smooth concave surface. A secondary south‑side tomb, divided into three compartments, bears passage‑tomb art on two of its stones. A third, smaller corbelled structure sits on the north‑west side, while a fifth chamber lies within the outer kerb to the east.
  • Hillfort ramparts – Walk along the surviving sections of the inner and outer banks. The northern rampart is the most intact, offering a tactile sense of the defensive work that once surrounded the cairn. Look for the faint magnetic anomalies that suggest a burnt palisade may have once topped the inner bank.
  • Panoramic views – From the highest point you can see the River Slaney, the town of Baltinglass, and the rolling hills of the Wicklow Mountains. On a clear day the distant silhouette of the Sugarloaf is visible.
  • Archaeological landscape – Rathcoran is part of a cluster of nine hillforts around Baltinglass, each with its own story. The site’s proximity to other prehistoric monuments – such as the nearby Baltinglass Abbey (Cistercian, 12th c.) and the Keadeen Mountain cairns – makes it an excellent base for a wider heritage walk.

Getting There & Visitor Info

  • Access – The monument is reached via a minor road that climbs from Baltinglass, about 2 km east‑north‑east of the town. A small car park sits at the end of the road; from there a short, un‑paved trail leads to the summit. The path is steep in places but suitable for most reasonably fit walkers.
  • Parking & Facilities – There is a basic free parking area near the trailhead. No toilet facilities or visitor centre are provided, so plan accordingly.
  • Accessibility – The route involves uneven ground, steep sections and a final scramble over scrub, so sturdy boots are recommended. The site is not wheelchair‑accessible.
  • Opening times – Rathcoran is a National Monument and is open year‑round with no admission charge. There are no staffed opening hours; visitors should be prepared to navigate independently.
  • Dog‑friendly – Dogs are permitted on the trail but should be kept under control, especially during the nesting season for ground‑nesting birds.
  • Safety – The hilltop can be exposed to wind; bring a wind‑proof layer and check the weather forecast before setting out.
