Llywelyn Ap Gruffydd Fychan
Llewelyn ap Gruffydd Fychan of Caeo (c.1341- 1401) was a wealthy Carmarthenshire landowner who was executed in Llandovery by Henry IV of England in punishment for his support of Owain Glyndwr's Welsh rebellion.
Until recently Llewelyn was little known even in his home area, but has become celebrated as a "Welsh Braveheart" after a campaign to construct a monument to him in Llandovery.
