Much fought-over seat of the kingdom of Deheubarth
Perched in a commanding hilltop position above the Tywi Valley, Dinefwr Castle occupies a similarly significant position in Welsh history. In the 12th century, the fortress was in the possession of The Lord Rhys, ruler of the ancient south Wales kingdom of Deheubarth. His reign saw a rare period of peace and stability that led to a flowering of Welsh culture, music and poetry.
Sadly, it was not to last. After Rhys’s death, conflicts over succession led to turbulent years as the Welsh princes fought amongst themselves and against the English. Dinefwr eventually fell into English control in 1287 and remained there for centuries, despite Owain Glyndŵr’s attempt to wrest it back during his uprising of 1403.
