At 8:58 am on December 21st, 1969, the first ray of direct sunlight shone through the roofbox and into the passage of Newgrange tomb, illuminating the floor up to the front of the basin stone. Brú na Bóinne is an archaeological landscape in Ireland that contains three large Neolithic passage tombs - Newgrange, Knowth, and Dowth. It has been designated a UNESCO World Heritage Site due to its outstanding universal value. The passage tombs were built around 5,000 years ago and show the earliest evidence of human activity in the area. They remained focal points for centuries after their initial construction and burials.
