Situated in the paddock of a cottage behind Knocksedan House. The mound is on the edge of a quarried area, which falls away N to the Ward River. It is a round-topped mound (dims.20.8m E-W; 20m W-S; H 1.4m). There is a local tradition that it contained burials. Ware in his Antiquities of Ireland recorded that ‘numbers of human bones are now to be seen lying promiscuously in this mound which was opened for gravel some years ago....about two years ago a human skeleton of monstrous size which measured from ankle to bone to the top of the cranium 8 foot 4 inches. The position of the head was from north to south and all the bones except the teeth were in a crumbling and decayed condition’.
