Medieval Wales: Dinefwr Castle

Carmarthenshire, Wales
(51.8768°N 4.0184°W)

12th century
Open to Public

Dinefwr Castle lies on a ridge on the northern bank of the River Tywi, with a steep drop of one hundred feet. It’s a Grade I listed building. The castle is an iconic place in the history of Wales.

It’s said that a castle was first constructed on this site by Rhodri the Great, although there’s no archaeological evidence to support this claim. It’s believed that Rhys ap Gruffydd, ruler of Deheubarth, (re)built it between 1155 and 1197. Llywelyn the Last gave Dinefwr to Maredydd, who allied himself to King Edward I of England. Maredudd had apparently been promised Dinefwr in return for his help, but Edward did not keep his promise and had Maredudd executed in 1291.

 In 1317 the castle was given to Hugh Despenser, the king’s favorite, and was later held by Sir Rhys ap Thomas, who carried out extensive rebuilding.

The castle is accessed through a fortified entrance protected by a battlement. A narrow spiral staircase leads to a high tower with extensive views of the Tywi valley to the south and west. The castle keep is entered via the cellar at its base.
