Pentre Ifan is the name of an ancient manor in the civil parish of Nevern, Pembrokeshire, Wales. It contains and gives its name to the largest and best preserved neolithic dolmen in Wales. The Pentre Ifan monument is a Scheduled Ancient Monument and was one of three Welsh monuments to receive legal protection under the Ancient Monuments Protection Act 1882. It is now in the guardianship of Cadw, with public access.

The Monument

As it now stands, the Pentre Ifan Dolmen is a collection of 7 principal stones. The largest is the huge capstone, 5 metres (16 ft) long, 2.4 metres (7.9 ft) wide and 0.9 metres (3.0 ft) thick.[2] It is estimated to weigh 16 tonnes[3] and rests on the tips of three other stones, some 2.5 metres (8.2 ft) off the ground.[3] There are six upright stones, three of which support the capstone. Of the remaining three, two portal stones form an entrance and the third, at an angle, appears to block the doorway.[4]

Original use

A possible reconstruction under the traditional theory as to its use

The dolmen dates from approximately 3,500 B.C. and has traditionally been identified as a communal burial. Under this theory the existing stones formed the portal and main chamber of the tomb, which would originally have been covered by a large mound of stones about 30 metres (98 ft) long and 17 m wide.[3] Some of the kerbstones, marking the edge of the mound have been identified during excavations. The stone chamber was at the southern end of the long mound, which stretched off to the north. Very little of the material that formed the mound remains.[3] Some of the stones have been scattered, but at least seven are in their original position. An elaborate entrance facade surrounding the portal, which may have been a later addition,[5] was built with carefully constructed dry stone walling. Individual burials are thought to have been made within the stone chamber, which would be re-used many times.[5] No trace of bones were found in the tomb, raising the possibility that they were subsequently transferred elsewhere.

Alternative theory

A major study by Cummings and Richards in 2014 has produced a different explanation for the monument.[6] They identify several distinctive attributes shared by the class of monument known as dolmens, all of which are particularly well exemplified at Pentre Ifan.

Firstly such monuments typically have a large capstone derived from a glacial erratic - far bigger than is required or sensible if the aim was to roof a chamber. Furthermore, the capstone has a flat underside. Sometimes, as here, this has been arrived at by splitting the rock, other times, as at Garn Turne, some 12 km to the south-west, it has been laboriously 'pecked' off using stone tools.[7] The capstone is supported on the tapering tips of slender uprights. As at Pentre Ifan, there are often other stones within the group, but they play no part in holding up the capstone, and the resulting effect of the enormous stone appearing to float above the other stones would seem to be deliberate and desired.[7] If these are the key elements of the monument then, it is argued, the stones were never designed to be buried within a mound, and they never formed a chamber to contain bones. What we see today is the monument as it was intended to be seen.[8] It might therefore represent a more elaborate version of a standing stone. Its purpose could be simply to demonstrate the status and skill of the builders, or to add significance and gravitas to an already significant place.[9]

Construction technique

The sheer size of the capstones of the larger dolmens makes it overwhelmingly likely that the stone was not brought in from elsewhere, but already stood as an independent glacial erratic on the same spot it now occupies. Evidence from the 1948 excavation is compatible with the idea of a large pit being dug at Pentre Ifan, to expose and work on the stone, perhaps splitting it to create a flat underside, It could then be levered vertically upwards a little at a time, using poles, ropes, and large numbers of people, and packed into place using a growing heap of boulders. Once at the required height, the supporting uprights could be introduced, and the boulders removed to leave only the uprights, and such other surrounding stones as were wanted.[10]


View of Portal

Pentre Ifan was studied by early travellers and antiquarians, and rapidly became famous as an image of ancient Wales,[11] from engravings of the romantic stones.[4] George Owen wrote of it in enthusiastic terms in 1603, and Richard Tongue painted it in 1835.[12] → The first United Kingdom legislation to give protection to ancient monuments was finally passed in 1882, and 'The Pentre Evan Cromlech' (as it was styled) was on the initial list of 68 protected sites - one of only three in Wales.[13] On 8 June 1884, 2 years after the passing of the first Ancient Monuments Act, Augustus Pitt Rivers, Britain's first Inspector of Ancient Monuments, made a visit and produced sketch plans of the monument.[1] The legal protection the act gave was limited. It became an offence to remove stones or items from the site, but the owner of a monument was exempt from any prosecution. The Act however provided for the Commissioner of Works to become 'guardian' of a scheduled monument[13] - in effect to own the monument even though the land on which it stands remains in private ownership. Perhaps as result of Pitt Rivers' visit, this protection was put in place, and the Commissioner of Works and his various successor bodies have been guardians of Pentre Ifan ever since.

Archaeological excavations took place in 1936/1937 and 1958/1959, both led by William Francis Grimes. This identified rows of ritual pits which lay under the mound, and therefore must pre-date it. Kerbstones for the mound were also found, but not in a complete sequence, and aligned more to the pits than the stone chamber.[12] Very few items were found in the excavations, other than some flint flakes, and a small amount of Welsh (Western) pottery.[12]

The dolmen is maintained and cared for by Cadw,[14] the Welsh Historic Monuments Agency. The site is well-kept and entrance is free. It is located about 17 km from Cardigan, and 5 km east of Newport, Pembrokeshire.
