The Hill of Tara (Irish: Cnoc na Teamhrach, Teamhair or Teamhair na Rí), located near the River Boyne, is an archaeological complex that runs between Navan and Dunshaughlin in County Meath, Ireland. It contains a number of ancient monuments and, according to tradition, was the seat of the High King of Ireland.
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 (double-ditched) ring fort and a bivallate 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 was constructed around 3,400 (cal.) BC.
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 artefacts dating from the 1st–3rd centuries.
Farther north is a long, narrow rectangular feature known as the Banqueting Hall (Teach Miodhchuarta), 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 declivity 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.
A church, called Saint Patrick's, is on the eastern side of the hilltop. The 'Rath of the Synods' has been partly destroyed by its churchyard.The modern church was built in 1822–23 on the site of an earlier one. The earliest evidence of a church at Tara is a charter dating from the 1190s. In 1212, this church was "among the possessions confirmed to the Knights Hospitallers of Saint John of Kilmainham by Pope Innocent III". A 1791 illustration shows the church building internally divided into a nave and chancel, with a bell-tower over the western end. A stump of wall marks the site of the old church today, but some of its stonework was re-used in the current church. The building is now used as a visitor centre.
