Three Wells Round Cairn is a prehistoric round cairn located in Wales and protected by Cadw under reference MM303. Round cairns of this type were constructed during the Neolithic or Bronze Age as burial monuments, typically comprising a mound of stacked stones heaped over a central grave or burial chamber. The monument's name references the locality and reflects the landscape that surrounds it.
The cairn sits upon Lower Devonian bedrock, composed of sandstone and conglomerate deposits that were laid down during the Early Devonian period over 400 million years ago. This underlying geology would have influenced the availability and type of stone used in the cairn's construction, with local stone sources worked into the mound by prehistoric builders. The interbedded nature of the sandstone and conglomerate would have provided varied material suitable for cairn construction.
As a scheduled ancient monument under Cadw's protection, Three Wells Round Cairn represents an important record of prehistoric funerary practice in Wales. Round cairns serve as visible reminders of early societies' monumental investment in commemorating and honouring their dead, and their presence across the Welsh landscape attests to sustained patterns of settlement and ceremonial activity spanning several centuries of prehistory.
