Princess Gwenllian Society

Princess Gwenllian (1282 - 1337) was the only child of Llywelyn the Last and Eleanor de Montfort. Llewelyn (the last native Prince of Wales) was killed by Edward I’s men in 1282 when Gwenllian was only six months old and she was abducted to a Priory at Sempringham in Lincolnshire. There she served as a nun for 54 years until her death.  

Abbey Cwm Hir Trust

Located in a remote valley in Powys, Cwm Hir was a large Cistercian abbey whose 75m nave was exceeded by only Durham and Winchester cathedrals in Britain. After Llewelyn the Last (the last native Prince of Wales) was killed by Edward I’s men in 1282 he was beheaded and his head was sent to London to be displayed on the Tower. His body was taken in secret to Cwm Hir Abbey and buried there.

Hywel Dda Centre, Whitland

According to tradition Hywel Dda called a great assembly of lawyers and leaders from all over his kingdom to the ‘Ty Gwyn-ar-Daf’ (the white house on the Taf), now known as Whitland, to study the laws of various provinces and to draw up a unified legal code for Wales. These laws, the ‘Laws of Hywel’ as they became known, are described as one of the wonders of Welsh history, and examples are displayed on slate plaques decorated with enamels in and around the gardens at the Centre.

Welsh Battlefields Society

Set up in 1997, this is the only Welsh Society devoted exclusively to the study of Welsh battles.

Cofio Llywelyn Society
