To experience the phenomenon on the morning of the Winter Solstice from inside Newgrange, visitors to Bru Na Bóinne Visitor Centre must enter an annual lottery at the centre. Of the tens of thousands who enter, sixty are chosen each year. Winners are permitted to bring a single guest. The winners are split into groups of ten and taken in on the five days around the solstice in December when sunlight can enter the chamber, weather permitting. (Due to the COVID-19 pandemic, however, the 2020 event shall be exclusively live-streamed with no public access.)
