45 Ancient Ruins That Are Even More Stunning Than the Pyramids

37. Newgrange (County Meath, Ireland): Europe's Megalithic Solar Alignment

Older than Stonehenge and the Egyptian pyramids, Newgrange is a monumental passage tomb in Ireland, dating back to roughly 3200 BCE. This massive circular mound, held in place by 97 kerbstones, conceals an inner passage leading to a cruciform chamber. Its true marvel is its precise alignment with the winter solstice; for just a few minutes each year, sunlight perfectly penetrates a "roofbox" above the entrance, illuminating the central chamber. This astonishing feat of prehistoric engineering speaks to an advanced astronomical understanding and complex spiritual beliefs.
