Waun Mawn

Waun Mawn (Welsh for 'peat moor') is a Neolithic stone circle site in the Preseli Mountains of Pembrokeshire, Wales. Following excavations in 2018, it was identified as a possible dismantled stone circle measuring approximately 110 metres (360 ft) in diameter, making it the fifth largest in Britain after Avebury, Stanton Drew, Karl Lofts, and Long Meg, and slightly larger than the Ring of Brodgar[1]. Located around 1.6 km southwest of Brynberian on the southern slopes of Cnwc yr Hŷdd (339m).
