Neolithic Tombs in

Glamorgan and Monmouthshire

by Martin J. Powell

Unlike many of the long cairns in the Black Mountains, most of the tombs in Glamorgan and Monmouthshire (Gwent) are terminally chambered, i.e. with a simple chamber positioned immediately behind the forecourt. There are also a number of ‘miscellaneous’ or hybrid types, displaying individuality in design and construction.

Two of the tombs in this list - Parc le Breos Cwm (SS 537 898) and Pen-Maen Burrows (SS 531 881) - have transepted chambers, where one or more pairs of side chambers branch off from the main passageway.

None of the tombs presented here have complex astronomical lines, all of them in fact representing the axis line of the main chamber and/or the long cairn. The best preserved (and restored) examples are Tinkinswood (ST 092 733) and Parc le Breos Cwm, the latter having recently been radiocarbon dated to a period around the middle of the fourth millennium BC (Whittle & Wysocki 1998).

• The following table is a summary of the survey results. For a more detailed examination of the chambered tombs in South Wales (together with site plans and excavation details) see the accompanying article on the 'Orientations of Neolithic Tombs in Glamorgan and Gwent Counties'.
