is known as Tobernaslath and sits beside a circular enclosure and standing stone. On the southwest side of the hill is a large, oddly-shaped limestone rock; a glacial erratic almost tall and thought to weigh over 30 tons. In prehistory an earthen bank was dug around it to mark it out as a special place. In Irish it is called the Ail na Míreann ("stone of the divisions"), as it is said to have been where the borders of the provinces met. It is nicknamed the Cat Stone, allegedly because it resembles the shape of a sitting cat. The biggest monument at Uisneach is Rathnew, the remains of a figure-of-eight shaped earthwork. An early medieval road leads towards Rathnew from the foot of the hill. Rathnew was originally one round enclosure marked by a ditch, with an eastern entrance. Inside it were several pits containing partly-burnt animal bones, each sealed with large flat stones. It appears that fires "had been kindled, and then suddenly quenched" with water or soil, in a ritual. There was also a large ash bed containing thoroughly-charred animal skeletons. This appears to have been "a sanctuary-site, in which fire was kept burning perpetually, or kindled at frequent intervals", where animal sacrifices were offered. Later, in the early medieval period, a large figure-of-eight shaped earthwork was raised on this site. It was a large round enclosure, with a smaller round enclosure joined to it, marked by a bank and ditch. Within each enclosure was a small stone building and a souterrain. It is suggested that Rathnew at this time was a place of royal and religious gatherings, and may have served as a royal residence of the kings of Meath during these gatherings. The Clann Cholmáin chieftains, who became kings of Meath, were styled "Kings of Uisnech" in early-medieval king lists. There is also Tuar Uí Cobhthaigh / Toorcoffey (Coffey's Tower) named after the brehon law O'Cobhthaigh family who were known as the filí or ollamhs of Uisneach. In Irish mythology In Irish mythology, Uisneach is described as the sacred centre of Ireland, the burial place of Irish gods such as Lugh and the Dagda, the site of a sacred tree (the Bile Uisnig), and a place of assembly (the mórdáil Uisnig) associated with the druids, which, according to later tradition, was held during the festival of Bealtaine.
