About the model
Newgrange (Sí an Bhrú), Brú na Bóinne, Co. Meath: a Neolithic passage tomb of c. 3200 BC - a cairn of water-rolled pebbles about 85 m across and 11 m high retained by 97 kerbstones, with a 19 m passage (22 + 21 orthostats) rising about 2 m to a cruciform chamber with a 6 m corbelled vault, three recesses and four basins, and a roof-box above the entrance that admits the winter solstice sunrise. Twelve stones of a Great Circle survive round it. The vault is original; the passage orthostats were straightened and the passage roof and roof-box dismantled and rebuilt in 1963-; the quartz-and-granite facade (to about 3 m), the kerb exposure, the curved entrance walls (modern, for visitors), a concrete wall behind the facade and a cowl over the chamber date from M. J. O'Kelly's excavation and reconstruction (1962-75) and later repairs (1984-88). Research file for a 3D model; quotes are exact text from the cited pages.
