Newgrange

Newgrange is the largest of the three tombs in the Boyne Valley. It consists of a roughly heart-shaped mound of turf and stones some 295ft/90m in diameter and 36ft/11m high, with a retaining curb of horizontal slabs. The vertical retaining wall is a reconstruction of the original based on the results of archaeological investigation. A few yards outside the curb there was originally a ring of 38 pillar stones, of which 12 survive.

The entrance to the tomb, marked by a curbstone on the southeast side with carved spiral decoration, leads into a narrow passage 66ft/20m long formed of 43 uprights between 5 and 8ft/1.5 and 2.4m high and roofed with massive lintels. At the end of the passage is the main tomb chamber, with a 20ft/6m high
