Carmarthen Castle was first built by Walter, Sheriff of Gloucester in the early 1100s. It was captured and destroyed on several occasions before being rebuilt in stone during the 1190s. The castle was captured by Owain Glyndŵr in 1405. Henry VII's father died at Carmarthen Castle in 1456. During the Wars of the Roses the castle fell to William Herbert and, during the Civil War, was captured by Parliamentary forces. It was dismantled by order of Oliver Cromwell in the mid 1600s.
It has been used as the site of Carmarthen's gaol until the 1920s. The remains of the castle were given a Grade I heritage listing in 1954 and is currently a tourist attraction and site of the town's Tourist Information Centre.
The castle is accessed today via the surviving 13-metre-high gatehouse on Nott Square or alternatively via the Old Castle Gaol entrance on Castle hill.
References:The Château de Foix dominates the town of Foix. An important tourist site, it is known as a centre of the Cathars. Built on an older 7th-century fortification, the castle is known from 987. In 1002, it was mentioned in the will of Roger I, Count of Carcassonne, who bequeathed the fortress to his youngest child, Bernard. In effect, the family ruling over the region were installed here which allowed them to control access to the upper Ariège valley and to keep surveillance from this strategic point over the lower land, protected behind impregnable walls.
In 1034, the castle became capital of the County of Foix and played a decisive role in medieval military history. During the two following centuries, the castle was home to Counts with shining personalities who became the soul of the Occitan resistance during the crusade against the Albigensians.
