Newgrange
About
A Neolithic passage tomb in the Boyne Valley of Ireland, built around 3200 BCE — older than Stonehenge and the Great Pyramid of Giza. The circular mound (85 meters in diameter) conceals a passage and chamber that is precisely illuminated by the winter solstice sunrise for approximately 17 minutes. The exterior is decorated with megalithic art, including the famous triple spiral (triskelion) carved at the entrance stone.
Significance
Newgrange is perhaps the most sophisticated astronomical monument in the prehistoric world — a 5,200-year-old stone structure precisely engineered so that sunlight travels through a roof-box above the entrance to illuminate the inner chamber for exactly 17 minutes on the shortest day of the year. This alignment, built a millennium before Stonehenge's sarsen phase, demonstrates extraordinary Neolithic astronomical knowledge and the primacy of the solar cycle in prehistoric Irish spirituality.
