The Labbacallee Wedge Tomb is more than ten meters long. It consists of 3 cover slabs, forming a rectangular chamber and a second, smaller, adjoining cavity. The gallery is then protected by a triple side wall, as well as by a row of stones about 1m30 high.
The site was reportedly excavated in 1934, revealing numerous remains of human bones as well as skulls that were buried there. Stone tools and fragments of pottery are also said to have been found there.
The site has the merit of being impressive: these cover slabs alone weigh more than 30 tons together. An impressive figure, which the research community is asking about. How was the tomb built? What means were used? Questions that remain unanswered to this day.
