Brú na Bóinne

Brú na Bóinne (Irish for Palace of the Boyne) is a World Heritage Site in County Meath, Ireland and is the largest and one of the most important prehistoric megalithic sites in Europe. It is a complex of Neolithic chamber tombs, standing stones, henges and other prehistoric enclosures, some dating from as early as 35th century BC - 32nd century BC. The site predates the Egyptian pyramids and was built with sophistication and a knowledge of science and astronomy, which is most evident in the passage grave of Newgrange. The site is often referred to as the "Bend of the Boyne" and this is often (incorrectly) taken to be a translation of Brú na Bóinne ( Palace of the Boyne).

The site covers 780ha and contains around 40 passage graves, as well as other prehistoric sites and later features. The majority of the monuments are concentrated on the north side of the river. The most well-known sites within Brú na Bóinne are the impressive passage graves of Newgrange, Knowth and Dowth all famous for their significant collections of megalithic art. Each stands on a ridge within the river bend and two of the tombs, Knowth and Newgrange appear to contain stones re-used from an earlier monument at the site. There is no in situ evidence for earlier activity at the site, save for the spotfinds of flint tools left by Mesolithic hunters.

However, the is evidence that this site was visited repeatedly during the Bronze Age, Iron Age, and Medieval periods, as evidenced by the multiple Beaker, Roman, and Medieval artefacts that were found during O'Kelly's excavations from 1962-1975.

Numerous other enclosure and megalith sites have been identified within the river bend and have been given simple letter designations, such as the M Enclosures. In addition to the three famous tombs, several other ceremonial sites constitute the complex including:

• Cloghalea Henge
• Townleyhall passage grave
• Monknewtown henge and ritual pond
• Newgrange cursus

Newgrange is the central mound of the Boyne Valley passage grave cemetery, but many other passage graves exist in the environs, including Knowth and Dowth which are of comparable size to Newgrange. Each of the three main megalith sites have significant archaeoastronomical significance. Newgrange and Dowth have Winter solstice solar alignments, while it is claimed Knowth has an Equinox solar alignment. In addition, the immediate environs of the main sites have been investigated for other possible alignments. The layout and design of the Brú na Bóinne complex across the valley has also been studied for astronomical significance.

As well as being surrounded on its southern, western and eastern sides by the Boyne, one of the Boyne's tributaries, the Mattock, runs along the northern edge, almost completely surrounding Brú na Bóinne with water. All but two of the prehistoric sites are within this river isthmus.
