Stone #75, pushed aside to gain entry, probably in the Iron Age, may be noted in the diagram found in the gallery at the bottom of the page. The triple-walled sides of the Labbacallee tomb are unusual; this feature may indicate the importance of those interred here. The excavators felt that some of the architectural features of the tomb had similarities to such monuments in the Paris region, perhaps suggesting a communication, or even a tribal affiliation between Munster and the north of France.
