Overview
Castleruddery Stone Circle sits on a gentle rise five miles north‑east of Baltinglass, just off the N81 in County Wicklow. The monument is an embanked stone circle – a henge – roughly 30 metres (about 100 ft) in diameter, surrounded by a low earthen bank about 1.2 m high. From the circle you can look eastward across the Glen of Imaal to Lugnaquilla, the highest summit of the Wicklow Mountains, and south‑west toward the River Slaney. The site is set in a field that is still grazed by sheep and cattle, giving it a timeless, pastoral feel.
History & Background
The circle dates to the later Bronze Age, roughly 2500 BC to 1500 BC, a period noted for elaborate metalwork, gold hoards and the construction of massive hill‑forts. Although it is not a tomb, the monument was likely an arena for meetings, rituals and possibly seasonal celebrations. Aerial photography has revealed an outer ditch and a second outer bank with a timber revetment, indicating that the original complex was far more elaborate than the stones alone suggest.
The two striking portal stones at the eastern entrance are made of white quartz, each weighing at least 15 tons. Quartz was a material of special significance in prehistoric ritual, believed to reflect and amplify light and energy. Their placement aligns the entrance almost due east, a direction that may have been used for astronomical observations, such as marking the sunrise at key times of the year.
Around forty stones originally formed the circle; today about 29 remain upright, with several smaller stones lying on the ground. Many of the stones bear cup‑marks and bullaun depressions – shallow basins that in Celtic tradition were used to collect rain‑water for healing or ceremonial purposes. One of the stones in the centre still displays a row of cup‑marks on its upper surface.
Name & Folklore
The Irish name Caisleán an Ridire translates as “Knight’s Castle”, a reminder of the medieval motte‑and‑bailey that sits just across the Glen Road from the stone circle. Local folklore holds that the stones were placed by supernatural powers and that the site possesses healing properties. The white‑quartz portal stones are still thought to retain a special energy, and the whitethorn (fairy tree) that wraps around one of the standing stones is often cited in stories of the Sidhe.
What to See & Do
- Quartz portal stones – Stand before the massive white‑quartz stones at the eastern opening. Their sheer size and the way they catch the morning light create a powerful visual impact.
- Earthen bank and outer ditch – Walk around the 1.2 m high bank to appreciate the concentric layout of the henge. The outer ditch, now faint, hints at the monument’s original defensive‑like setting.
- Cup‑marked and bullaun stones – Look closely at the stones with cup‑marks; these prehistoric carvings add a mysterious, tactile element to the site. Some of the bullauns are still partially filled with water after recent rain, offering a glimpse of ancient ritual practice.
- Landscape vistas – From the centre of the circle, turn slowly to locate nearby landmarks such as Spinans Hill, a substantial hill‑fort, and the distant peaks of the Wicklow range. The alignment of the portal stones frames the sunrise over Lugnaquilla on clear mornings.
- Wildlife and flora – The surrounding field is dotted with hawthorn and whitethorn trees. Occasionally a whitethorn’s roots will clasp a standing stone, creating a striking natural sculpture.
Access & Transport
The monument is a National Monument (No. 441) in state ownership and is free to visit. Access is via a sharp right‑hand turn off the N81, sign‑posted for the stone circle. A small roadside lay‑by provides parking; the lay‑by can fill quickly in summer, so arriving early is advisable.
By car – From Dublin, take the M50 to the N11 southbound, then the R755 to Glendalough and continue on the R756 for about 7 km. Look for the Castleruddery sign on the left.
Public transport – Take a Dublin‑to‑Wicklow bus (e.g., Bus Éireann route 133). In Wicklow town change to a local service towards Glendalough (route 133/134). Ask the driver to drop you near the R755 junction; the stone circle is a 2 km walk from there.
Walking – For the more adventurous, the circle can be reached on foot from the village of Laragh via the R756 (about 7 km, 1½‑2 hours).
