Cefn Gwernffrwd

Primary Reference Number (PRN) : 7434
Trust : Dyfed
Community : Cilycwm
Unitary authority : Carmarthenshire
NGR : SN73724942
Site Type (preferred type first) : Bronze Age Stone Row
Status : Scheduled Monument

Summary :
One of a group of five prehistoric ritual monuments, the others being 7433 (a ring barrow), 7432 ( a stone circle), 7636 (a possible stone row) and 7431 (a round barrow). All four sites are located on top of a ridge in what was once open moorland which is now afforested, although the site has been left clear of trees. Access to the large unplanted area where these monuments lie is best gained up the eastern of the two firebreaks from the track to the SW which begins at Bwlch-y-rhiw. This site is a row of three stones just to the E of the ring barrow and are similar to the row of three stones (7636) to the W of the stone circle lying between the circle and the round barrow.

Description :
This is a row, 4m long, of three stones just to the east of ring barrow PRN 7433. The row is aligned northeast-southwest and consists of three earthfast stones of similar dimensions. The southwest stone measures approximately 0.66m high x 0.3m x 0.3m at its base, although it tapers to 0.26m x 0 .2 m at the lop. The middle stone is set towards the northeast end and it measures 0.66m high x 0.5m x 0.3m. The northeast stone is lightly shorter than the others, 0.57m high x 0.3 x 0.3. The tops of all threes stones have been rounded through weathering. The positions of the stones meant that there is a significant difference in the size of the gaps between the southwest and middle stones, 2.5m. and the middle and northeast stones, less than 1m. This suggests that there may originally have been a fourth stone between the southwest and middle stones. The row has been compared to a second stone row reported in this area (PRN 7464), which has now apparently been lost. One of a group of five prehistoric ritual monuments, the others being a ring barrow (PRN 7433), a stone circle (PRN 7432) and a round barrow (PRN 7431), which are located on top of a ridge in what was once presumably open moorland, but which is now afforested. Even though the site has been left clear of trees the northeast end is within 1.5m of the edge of the forest. It is becoming overgrown by long tussocky grass. N Cook PFRS 2003

Aligned towards a dip in the horizon between Bryn Cadwgan + Carn Nant-yr-Ast. Magnetic reading along this line approx 235º to 238º Azimuth range within which alignment falls, covers the 229.5º azimuth of winter solstice at Stonehenge.
