I'm amazed that this beautiful video showing the solstice sunlight in the chamber of Newgrange hasn't had more views on YouTube. Currently, it only has 112 views. This is the sort of video that is extremely rare, because it's so difficult to get into Newgrange on the solstice and usually only the press photographers are allowed in, and they don't usually do video. This video puts you right in the chamber, at that special moment. There are some shots closer to the entrance too. Really beautiful stuff. Well worth a look.
