SMR No.: ME019-045----
Monument Type: Megalithic tomb - passage tomb
The great mound of Newgrange is delimited by a megalithic kerb. It covers a cruciform passage-tomb, 24m long, opening to SE. The chamber is roofed with a fine corbelled vault. There are two stone basins in NE recess; the others contain single basins. The 'roof box' above, some 2.4m back from the passage entrance, permits rays of the rising sun at midwinter solstice to penetrate to the chamber. Many of the kerb stones and a great number of the structural stones of the passage and chamber bear megalighic art. A circle of standing stones (ME019-045005-) surrounds the mound, and three small passage-tombs (ME019-046001-, ME019-046003--, ME019-044004-) are in close proximity to it.
