The alignment of Newgrange is special because on the winter solstice, the sun shines directly down the passageway to the chamber, illuminating the interior and symbolizing the rebirth of the sun. This alignment was carefully planned by the Neolithic builders thousands of years ago. On the summer solstice, the sun also shines directly down the passageway to the chamber, marking the longest day of the year. Additionally, on rare occasions, the moon also aligns with the passageway on the winter solstice, casting a unique lunar light into the chamber. This alignment shows the advanced astronomical knowledge and precision of the ancient builders of Newgrange.
