The Loughcrew Cairns (Sliabh na Caillí, 'The Witch's Mountain') in County Meath are a magnificent complex of over 30 Neolithic passage tombs dating to approximately 3500-3300 BC, making them older than the Egyptian pyramids. Spread across four hilltops, the cairns are rich with megalithic art — spirals, concentric circles, and solar symbols carved into the ancient stones. Local fairy folklore is deeply embedded in the landscape. The cairns are traditionally associated with the Cailleach (the divine hag or witch-goddess of Celtic mythology), who is said to have created the hills by dropping stones from her apron as she leaped from peak to peak. The main tomb, Cairn T, is astronomically aligned so that sunlight illuminates the decorated back stone during the spring and autumn equinoxes. For millennia, local people treated the cairns as fairy dwellings, leaving offerings and avoiding the site after dark. The site represents one of the most remarkable intersections of ancient astronomy, sacred art, and living folklore in Europe.
