The Hill of Uisneach or Ushnagh ( or ) is a hill and ancient ceremonial site in the barony of Rathconrath in County Westmeath, Ireland. It is a protected national monument. It consists of numerous monuments and earthworks—prehistoric and medieval—including a probable megalithic tomb, burial mounds, enclosures, standing stones, holy wells and a medieval road. Uisneach is near the geographical centre of Ireland, and in Irish mythology it is deemed to be the symbolic and sacred centre of the island. It was said to be the burial place of the mythical Tuatha Dé Danann, and a place of assembly associated with the druids and the festival of Bealtaine. The summit is above sea level and lies north of the R390 road, 8 km east of the village of Ballymore and beside the village of Loughnavalley. The hill occupies parts of four adjacent townlands: Ushnagh Hill, Mweelra, Rathnew, and Kellybrook. Name The hill is called Uisneach in both Irish and English, with the alternative Irish name Cnoc Uisnigh meaning "hill of Uisneach". It is also anglicized as 'Ushnagh', such as in the name of the townland. In Old and Middle Irish it was spelt Uisnech. Eric P. Hamp derives the name from Proto-Celtic *us-tin-ako- meaning "place of the hearth" or "place of cinders". T. F. O'Rahilly derived it from *ostinako- meaning "angular place". Features The site consists of a set of monuments and earthworks spread over two square kilometres. About twenty are visible, and the remains of at least twenty others have been identified under the ground. They include a probable megalithic tomb, burial mounds, enclosures, standing stones, holy wells and a medieval road. They date from the Neolithic to the early Middle Ages, showing that the site has been the focus of human activity for about 5,000 years. Several sites were excavated in the 1920s by R.A.S. Macalister and R. Praeger. The summit has panoramic views, from which hills in at least twenty counties can be seen. On the summit is the remains of a probable megalithic tomb, known as 'St Patrick's Bed', which was once surrounded by a ring ditch. Downslope to the east is a small lake known as Loch Lugh or Loch Lugborta, and on a rise east of this is a burial mound known as Carn Lughdach, which was also once surrounded by a ring ditch. South of these are two holy wells, one of which
