Pentre-Ifan in Pembrokeshire was the first prehistoric burial chamber to be placed under state guardianship in 1880.
The earliest guide to a chambered tomb in Wales was the one on Bryn Celli Ddu on Anglesey by Wilfrid James Hemp (1935).
This was followed by H.N. Savory’s Tinkinswood and St Lythan Long Cairns in the Vale of Glamorgan (1950), and William F. Grimes’ two guides for Pentre Ifan in Pembrokreshire (1953) and Capel Garmon in Gwynedd (1958).
Savory, Keeper of Archaeology at the National Museum of Wales, also contributed the essay on ‘Prehistory’ for the Illustrated Guide to the Ancient Monuments of Wales.

Parc Le Breos on Gower in south Wales has an extended entry in Diane M. Williams, Gower: A Guide to Ancient and Historic Monuments on the Gower Peninsula (1998). This is one of the Cotswold-Severn tombs (e.g. Hetty Pegler’s Tump).
The most recent guide is for Capel Garmon by M.J. Yates (1996). This consists of a foldout card with images and plan.
