1. Carreg Samson or Garn Wen burial chambers are three closely grouped burial chambers set in a north-south line (Dat Prn2908). All three monuments appear to have had a capstone partly earthbound and partly supported. Carreg Samson is the largest of the capstones, being 4.0m by 3.2m and there is a trace of a probable mound against its north side.
