The engraving in the Loughcrew passage grave. Loughcrew Cairns form the largest complex of Passage Graves in Ireland. The Cairns are megalithic structures containing symbolic engravings. Like other passage graves in Ireland, they have clear astrological alignments. There is evidence of many uses during the millenia, but it is generally agreed that they were originally built about 4000 bc as burial chambers. That’s over 6000 years old!!
