Spent the afternoon exploring Newgrange & Knowth yesterday. These passage tombs are older than they Egyptian pyramids, dating back 5000 years ago, built during the Neolithic period. Newgrange is perfectly aligned with the direction of the Winter Solstice Sun which beams up through and illuminates the chamber for approximately 17 minutes. Pretty amazing site to see, and mind boggling how they constructed these tombs back in those days.
