The Hill of Tara (Irish Teamhair na Rí, "Hill of the Kings"), located near the River Boyne, is an archaeological complex that runs between Navan and Dunshaughlin in County Meath, Leinster, Ireland. It contains a number of ancient monuments, and, according to tradition, was the seat of Árd Rí na hÉireann, or the High King of Ireland. Current scholarship based on the research conducted by the Discovery Programme, indicates that Tara was not a true seat of Kingship, but a sacral site associated with Indo-European Kingship rituals.
At the summit of the hill, to the north of the ridge, is an oval Iron Age hilltop enclosure, measuring 318 metres (1,043 ft) north-south by 264 metres (866 ft) east-west and enclosed by an internal ditch and external bank, known as Ráith na Ríogh (the Fort of the Kings, also known as the Royal Enclosure). The most prominent earthworks within are the two linked enclosures, a bivallate ring fort and a bivallete ring barrow known as Teach Chormaic (Cormac's House) and the Forradh or Royal Seat. In the middle of the Forradh is a standing stone, which is believed to be the Lia Fáil (Stone of Destiny) at which the High Kings were crowned. According to legend, the stone would scream if a series of challenges were met by the would-be king. At his touch the stone would let out a screech that could be heard all over Ireland. To the north of the ring-forts is a small neolithic passage tomb known as Dumha na nGiall (the Mound of the Hostages), which dates to ca. 2000 BC.
The Lia Fáil (Stone of Destiny)To the north, just outside the bounds of the Ráith na Rig, is a ringfort with three banks known as Ráith na Seanadh (the Rath of the Synods). Excavations of this monument have produced Roman artifacts dating from the 1st-3rd centuries.
Further north is a long, narrow rectangular feature known as the Banqueting Hall, although it is more likely to have been a ceremonial avenue or cursus monument approaching the site, and three circular earthworks known as the Sloping Trenches and Gráinne's Fort. All three are large ring barrows which may have been built too close to the steep and subsequently slipped.
To the south of the Royal Enclosure lies a ring-fort known as Ráith Laoghaire (Laoghaire's Fort), where the eponymous king is said to have been buried in an upright position. Half a mile south of the Hill of Tara is another hill fort known as Rath Maeve, the fort of either the legendary queen Medb, who is more usually associated with Connacht, or the less well known legendary figure of Medb Lethderg, who is associated with Tara.
