Loughcrew/Sliabh na Caillaigh is group of neolithic passage tombs like Newgrange. Theyre older and more technologically advanced than the pyramids at Giza and the non representational art on the tombs doesnt occur again in europe until the 19th century.
Loughcrew is different to newgrange. Loughcrew is aligned to the equinoxes rather than the solstices so for the week of the equinox sunlight travels into the heart of the passage tomb and lights up a chamber thats been dark except for those times for more than 5000 years
Loughcrew is also older than newgrange and might be the product of a different tribe of the same ethnic group. While Loughcrew faces sliabh Gullion mountain in Armagh in Ulster, Newgrange faces the Wicklow mountains in Leinster and is decorated with quartz quarried there.
Loughcrew was in use much longer than newgrange. It was occupied in the Iron Age and might have been both a slaughter site and site for workshops. There have been la tene decorated tools made from iron and bone found there that people cant figure out a use for.
Today its the home of the cultic cailleach, an expression of the feminine divine in Irish cultures that may have roots in polytheism. She shapes the landscape, The shape shifts, is ancient, supernaturally strong and fertile and a source of knowlege. Shes even immanent in grain harvests.
Everything enigmatic and man made in the landscape is built by her. Theres a story that the Cailleach was building a round tower until a little boy looking up at her shouted haha I can see your bum. Then she dropped to the ground giving out to the kid that she wouldve built it to the sky if he hadnt been so cheeky.
