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.
[3] 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.
[2] 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.
