It is the largest dolmen (portal tomb) in County Waterford exhibiting a double capstone configuration, though it is not the tallest standing stone structure.

The orthostats (upright stones) measure up to 2.8 metres (9 ft 2 in) in height around a tightly closed interior chamber.

[4] The interior chamber is accessed by a keyhole entrance at ground level, 0.8 metres (2 ft 7 in) in width, which may suggest spiritual offerings were placed inside the structure in ancient times.

This gives rise to the possibility of solar and lunar alignments during summer solstice and full moon cycles of the start and middle of the year.

[6] The monument was once part of the cemetery of Kilbride Church, circa 18th century (now located in ruins in the northerly field), which has been reconstituted as pasture for cattle.
