For a few days each year, around the winter solstice, the sun as it sinks below the horizon shines down the long passage into the mound at Maes Howe in Orkney and lights up the far wall of the inner chamber. We have crawled along this low tunnel in summer (mind your head) and even then the experience was impressive.
There is a webcam placed to catch the moment. Right now (11.22 am on 20th Dec) there is just a dim patch of light, but at sunset tomorrow (21st) the last rays of the sun will shine on the back of the chamber.
