Who it was built by
Newgrange was built by a farming community that prospered on the rich lands of Boyne valley. Knowth and Dowth are similar mounds that together with Newgrange have been designated a World Heritage Site by UNESCO. Archaeologists classified Newgrange as a passage tomb, however Newgrange is now recognised to be much more than a passage tomb. Newgrange is a large kidney shaped mound covering an area of over one acre, retained at the base by 97 kerbstones, some of which are richly decorated with megalithic art. The 19 metre long inner passage leads to a cruciform chamber with a corbelled roof.
Newgrange is part of a large complex of monuments built along a bend of the River Boyne known collectively as Brú na Bóinne. The other two principal monuments are Knowth (the largest) and Dowth, but throughout the region there are as many as 35 smaller passage-tombs and many other sites of great archaeological importance and interest.Dowth is the least well-known of the three great tombs of the Boyne Valley. It has not yet been excavated, but initial investigations reveal two passage tombs within the mound.
