The huge rocks
of Henblas 'dolmen' are curious sight and it is debatable whether they
were part of a man made structure or simply glacial erratics deposited
near the edge of a plateau above the river Hen Afon Cefni. Standing
in pasture in the now abandoned Henblas Country Park the monument consists
of a pair of massive quartz rich boulders with a further large slab
lying between them that has been interpreted as being a former capstone
- whether this capstone actually once balanced on the two boulders is
also questionable. The boulders which measure about 4 metres and 3 metres
in height are probably in their original positions but it has been noted
that the capstone which is nearly 4 metres square has scratch marks
or 'striations' that do not match the direction of the known ice flows
in the area leading to the suggestion that it has been moved by human
hands. It is possible then that the capstone was added to the existing
rocks to create a chambered
tomb, unconfirmed reports from the 19th century claim that at least
one other stone stood nearby and this may have formed part of an entrance
passage from the east. These same reports also claim that an urn
full of cremated ashes as well as more ash under a stone slab and a
possible blue faience
bead were found at or near to the site.
