The heavily disturbed Portal Tomb of Ballyhenebery (in Irish, Baile Hinibeire) is located north of Piltown (in Irish, Baile an Phoill), 250 m west of the Pil River, a small stream in County Kilkenny, Ireland, which flows into the River Suir. Portal Tombs are megalithic structures found in Ireland and Britain, characterized by two equally tall, upright stones with a doorstone in between, forming the front of a chamber covered, in part, by a massive capstone.
The massive capstone of the Portal Tomb, partly lying on the ground, measures approximately 5.1 m in length, 3.3 m in width, and 0.7 m in thickness. It rests on the 2.2 m long southern portal stone, adjacent to the possibly southeast-oriented chamber. A small fragment of the northern portal stone is visible. The Portal Tomb is situated on a hill of about 10.0 m in diameter and 2.0 m in height, with a large tree growing on the western side.
