Meini gwyr      Meini Gwyr: (Henge-Circle IC).

The Meini Gwyr monument is unique in Welsh prehistoric architecture, being the only known raised henge-circle.

Sadly, all that remains of this once impressive construction is two lone stones in a field.

The location of this important 'ceremonial' structure so close to the source of the Stonehenge 'Bluestones' and the Gors Fawr circle make it likely that it was once an integral part of the local Neolithic landscape

   Meini Gwyr: ('Buarth Arthur')

Meini Gwyr has been almost entirely demolished over the centuries, with the last two combining to cause more damage than the previous thirty or forty. The notice board at the gate describes the state of the site a couple of hundred years ago as a henge combined with a circle of large stones, and an entrance-way of more than usual complexity, consisting of a stone-lined passage through the earth bank.

Sketch made by William Stukeley (1687-1765).


'The embanked, sub-circular enclosure at Meini Gwyr measures c.20-22m in diameter, having a NW facing entrance. An excavation in 1938 showed that two extant stones were the survivors of 19 stones that originally ringed the interior of the earthwork. The entrance was lined by a 'palisade' of lesser stones, whilst e.19th century reports speak of two avenues of stones approaching the enclosure'. (1)

The text on the information sign (supplied by the Dyfed Archaeological Trust Ltd) reads as follows:

Meini Gwyr, also known as Buarth Arthur, is an embanked stone circle probably dating to the transition between the late Neolithic and early Bronze Age periods. The site is likely to have been used for religious rituals.

According to a late 17thC account by Edward Lhuyd, there were then fifteen stones in the circle ranging in height from three to six feet, but a further seven or eight were thought to have been 'carried off'. Apparently, there was also an entrance lined by smaller slabs.

The site was partially excavated in 1938 by Professor W.F. Grimes. Unfortunately most of the records were destroyed in a bombing raid on Southampton in 1940. The plan is based partly on ground and air photographs of the excavation. Grimes established that the circle, some 60 feet in diameter, originally consisted of 17 stones which, like the two surviving ones, were set at an angle into the inner slope of the bank about 3 feet height and 120 feet in the external diameter, with no trace of a ditch. The excavations confirmed that the entrance through the earthwork was formerly flanked by upright stones, set in a trench. The bank was set with stone curb extending for some 30 feet on either side of the entrance, in front of which was a clay-filled pit containing a large quantity of charcoal. There were no features or finds recorded from the interior, though this was only partly examined. Some fragments of early Bronze Age pottery came from a hearth set in a deep depression on the southeast bank.

Meini Gwyr stands at the centre of 'West Wales' most important complex of Neolithic and Bronze Age ritual and funerary monuments, lying on a ridge-way linking the wester end of the Preselis to the eastern Cleddau river and Milford Haven. This was a route by which the bluestones for Stonehenge may have been transported. Included in the complex are several Bronze Age burial mounds and cairns or various forms, and a 'henge' monument (akin to early elements at Stonehenge). Also, there is the site of 'Yr Allor' ('The Altar') comprising two, formerly three standing stones some 200 yards west of Meini Gwyr and apparently known by the 17thC. These stones may be the remains of a chambered tomb.

Carn Meini, a source of the bluestones lies only 3 miles to the north. The site's name - 'Meini' ('large stone') and 'Gwyr' ('crooked') may refer to the varying size, shape or angle of the stones set in the circle. These were not 'bluestones' but another form of volcanic rock. Many such boulders are found locally and were originally deposited by glacial action. The alternative name 'Buarth Arthur' ('Arthur's Yard') is an example of a common legendary association of this figure with prehistoric stone monuments and is not regarded as significant.

Note: The nearby standing stones called the 'Altar' are on private land.
