Lonely Planet review
To the south of the church, the Royal Enclosure is a large, oval Iron Age hill fort, 315m in diameter and surrounded by a bank and ditch cut through solid rock under the soil. Inside the Royal Enclosure are several smaller sites.
The Mound of the Hostages , a bump in the northern corner of the enclosure, is the most ancient known part of Tara, but is closed to the public. A treasure trove of artefacts was unearthed, including some ancient Mediterranean beads of amber and faience (glazed pottery). More than 35 Bronze Age burials were found here, as well as extensive cremated remains from the Stone Age.
Although two other earthworks within the enclosure, the Royal Seat and Cormac's House , look similar, the Royal Seat is a ring fort with a house site in the centre, while Cormac's House is a barrow (burial mound) in the side of the circular bank. There are superb views of the surrounding Boyne and Blackwater Valleys from here.
Atop Cormac's House is the phallic Stone of Destiny (originally located near the Mound of the Hostages), which represents the joining of the gods of the earth and the heavens. It's said to be the inauguration stone of the high kings, although alternative sources suggest that the actual coronation stone was the Stone of Scone, which was removed to Edinburgh, Scotland, and used to crown British kings. The would-be king stood on top of the Stone of Destiny and, if the stone let out three roars, he was crowned. The mass grave of 37 men who died in a skirmish on Tara during the 1798 Rising is next to the stone.
