Overview
Grange Stone Circle stands as one of Ireland’s most impressive Bronze-Age monuments, located just 300 metres west of Lough Gur in County Limerick. Recognised as the largest stone circle on the island, it features 113 contiguous standing stones arranged in a near-perfect ring roughly 45 metres in diameter. An earthen bank, about 9 metres wide and 1.2 metres high, encircles the stones, giving the site a distinct henge-like character. The monument sits on open public land and is free to visit year-round.
History & Archaeology
The circle dates back approximately 4,000 years to the late Bronze Age. Archaeological evidence suggests it was laid out from a central point using a rope, a technique confirmed by the discovery of a central post-hole. Excavations in 1939 revealed thousands of Beaker pottery fragments, two hearths, animal bones, and unburnt human remains, indicating the site served as both a ritual gathering place and a burial ground. Twelve larger orthostats are spaced at regular intervals around the ring, each paired with an opposing ‘axial’ stone to create a carefully planned ceremonial layout.
The monument’s primary astronomical feature is its eastern entrance, which aligns with the sunset on the festival of Samhain (early November). This solar orientation mirrors several henge sites across Britain and Ireland. In August 2022, archaeological photographer Ken Williams documented previously unseen petroglyphs on one of the stones, including concentric circles, arcs, and what appears to be a human figure. These markings are rare in Munster and have drawn comparisons to the famous rock art at Newgrange and Knowth.
What to See & Do
The most striking feature of the site is Rannach Chruim Duibh (Crom Dubh’s Division), a massive monolith standing over 4 metres tall and weighing an estimated 40 tonnes. Visitors can walk the inner perimeter to view the contiguous stones up close, then explore the smaller secondary circle to the north-north-east and a notable leaning standing stone further north.
The site is particularly atmospheric during early morning or late afternoon when low light casts long shadows across the monoliths. Photographers often use a wide-angle lens to capture the full 45-metre diameter, while a telephoto lens helps isolate individual stones and the newly discovered carvings. For those interested in the petroglyphs, low-angle lighting at dawn or dusk can help reveal the faint markings without the need for artificial equipment.

Folklore & Local Legend
Local tradition associates the site with the sun goddess Gráinne, reflected in the Irish name Lios na Gráinsí (“Fort of the Grange”). A solitary fairy tree grows near a stone in the secondary circle; folklore warns against disturbing it, as it is considered a portal for the Aos Sí (fairy folk). The surrounding Lough Gur landscape is also steeped in legend, with stories linking the lake to the goddess Áine and the historic Fitzgerald family.
Nearby Attractions
Grange sits within a dense archaeological landscape. Within walking distance, you can visit the Lough Gur Visitor Centre & Lakeshore Park for interpretive displays and café facilities, as well as the nearby Lough Gur Wedge Tomb and the ring-cairn on Knockfennel Hill. For a broader day trip, Adare Castle lies approximately 18 km north-west, offering medieval fortifications and historic gardens.
Grange Stone Circle remains an unguided National Monument maintained by the Office of Public Works. Visitors are asked to stay on marked paths, avoid climbing or moving stones, and respect the quiet atmosphere of the site. The monument is open year-round with no entry fee, making it a straightforward stop for anyone exploring the Lough Gur heritage trail.
