Ireland’s early farmers raise over a thousand megalithic tombs
Ireland’s megalithic tombs, built around 3500 B.C.E., reveal a remarkable feat of Neolithic engineering. Farming communities raised over 1,000 monuments across the island, including Newgrange in the Boyne Valley, whose passage aligns so precisely that winter solstice sunlight still reaches the inner chamber each December. They built for the dead on a scale meant to speak across millennia.
