Bodowyr Burial Chamber is the central burial chamber of a passage grave of a type more frequently found in Ireland. The chamber has three upright stones about a metre high supporting a robust, wedge-shaped capstone. A large stone lying flat nearby on the western side may have been part of the structure, perhaps another upright, or a blocking stone, and another low stone beside the entrance to the east which was perhaps a kerb or sill. Originally a mound of earth or rubble would have covered or partially covered the dolmen, and there would have been a passage from the entrance on the southeast to the side of the mound. The mound has since been completely dispersed. The location is on level, low-lying ground and it is not apparent why this particular site should have been chosen. The fact that Snowdon and the Glyderau are visible in the distance, with the Llanberis Pass between them, may be significant, and there may be some solar or lunar alignment as seen from the entrance that has not yet been elucidated.
