Newgrange (passage tomb)

Newgrange is an ancient passage tomb located in Ireland, built around 3200 BCE, making it older than Stonehenge and the Egyptian pyramids. It features a large mound with a central passage leading to a chamber where burials likely took place. The structure is expertly aligned so that during the winter solstice, the rising sun illuminates the inner chamber through a specific opening, demonstrating advanced understanding of astronomy. Its construction reflects significant social and spiritual importance for its creators, serving as a ritual site and a monument to their ancestors and seasonal changes.
