One of the most famous prehistoric sites in the world and the most famous of all Irish prehistoric sites. Newgrange was built in such a way that at dawn on the shortest day of the year, the winter solstice, a narrow beam of sunlight for a very short time illuminates the floor of the chamber at the end of the long passageway.
Originally built between c. 3300 and 2900 BC, which means that it is over 5,000 years old.
