Carreg Samson  Carreg Samson (also known as "Carreg Sampson", "Samson's Stone", or the "Longhouse") is a 5000-year-old Neolithic dolmen located half a mile west of Abercastle near the Pembrokeshire Coast Path in Wales. It is called "Samson" because of a local legend that Saint Samson of Dol placed the capstone in position with his little finger. Carreg Samson has a capstone, 4.7 metres by 2.7 metres and 1.0 metre thick. The capstone rests on three of six stones 1.1 to 2.2 metres high. The whole burial chamber was once covered by a mound of earth or stones and once these were removed stones were used to block the holes in the sides of the tomb so that it could be used as a shelter for sheep. The site was excavated in 1968 which revealed four additional stone-holes, one having supported a further chamber stone, the others indicating a possible passage leading off to the northwest. Slight traces of a covering cairn were found to the south and it was shown that the monument had been raised over a pit 0.8 metres deep, filled with clay and stones. Finds included a small quantity of burnt bone, pottery, and flints.
