The stone circle comprised 13 stones set in a circle with a diameter of 30 ft. Four out of the 13 stones are missing and three were re-erected after excavation. Two portal stones are set radially on an east–west axis to the recumbent stones and are 240 cm high. At just under 8 ft, these stone are among the tallest of any Irish stone circle. The axis from these stones to the large axial-stone on the west side, points to sunset at the equinoxes.^[1] Many of the stones have quartz inclusions and many small pieces of quartz are associated with the circle.^[3]

A boulder burial is sited 20m east of the circle, and its large capstone (weighing almost 20 tons^[3]) has seven or more small cup-marks on the upper surface. Two of the three small supporting stones are of quartz and a fourth has been uprooted. A nearby loose slab also features cup-marks. The complex, which included a wooden house (which had been excavated) is of Bronze Age date.^[1]

In 1959 the site was excavated and a central pit containing charcoal and cremated bone was found.^[3]
