[Ir., royal fort, fortress of kings].
Site of old earthworks, former citadel, on the west bank of the Barrow River near Leighlinbridge, Co. Carlow, with rich associations in early Irish literature. T. F. O'Rahilly (1946) asserted that Dind Ríg might have been known to Ptolemy (2nd cent. ad) as Dunon. Most often it is seen as the fortress of south Leinster kings and their most ancient place. The Fir Bolg king Sláinge was thought to be buried here, and thus it is sometimes known as Duma Sláinge/Sláine. Dind Ríg is also known as Tuaim Tenba. In the best-known story, Orgain Denna Ríg [The Destruction of Dind Ríg], Labraid Loingsech burns the citadel to the ground. Ramparts of the remaining earth-works are 237 feet in diameter.
