- Cairn G: This is the showstopper. Its roofbox, aligned to the midsummer sunset, is a rare architectural feature — the only other known example being at Newgrange, which aligns to the winter solstice sunrise. The triple-chambered design inside Cairn G reflects a sophisticated ritual layout, likely tied to beliefs about death and rebirth.
- Cairn H: Though more eroded, it still holds its place in the ceremonial landscape. Its ruinous state adds a haunting beauty, as if time itself has softened its edges.
- Cairn K: With its 7-meter passagfe pointing towards Queen Maeve's cairn on Knocknarea, this alignment suggests a deliberate connection between sacred sites — possibly reflecting mythological or ancestral ties.
- Cairn L: Often overlooked, but it completes the quartet at the summit and adds to the sense of a planned necropolis.
Visiting Tips
- The walk from the car park is steep but rewarding. Good footwear is essential, and the weather can change quickly — so layers help.
- The tombs are fragile and sacred.
