For anyone interested in ancient history this is a fascinating place to visit. In the summer months you can actually go inside the cairn. Clusters of Megalithic Cairns are dotted around the Slieve na Caillaigh hills at Loughcrew, the main concentrations are on Carnbane East where Cairn T is the centrepiece and Carnbane West where Cairn L is located. The illumination of the passage and chamber at the Winter solstice sunrise in Newgrange is world famous. Less well known is the Equinox illumination at sunrise in Cairn T at Loughcrew. The backstone of the chamber is illuminated by a beam of light at sunrise on the Spring and Autumnal Equinoxes.
