The Gleninsheen Wedge Tomb is a fine example of the transition beween Stone and Bronze Age cultures. Like Poulnabrone Dolmen, this tomb has the familiar platform slab supported by parellel raised support stones. This was the doorway into the tomb.

This tomb is located north of Poulnabrone on the same road, the R480. A small sign marks the way to the Gleninsheen area on the east side of the road.
