Kidwelly Castle is a Norman castle overlooking the River Gwendraeth. The origin of this surname traces back to when it was spelled Cygweli which means 'swan.'
The present remains of the castle date from the early 12th century. Created as a defence against the Welsh, the castle fell to the Welsh several times in the twelfth century. Later in its history, it was unsuccessfully besieged by forces of Owain Glyndŵr in August 1403 with assistance from soldiers from France and Brittany who captured Kidwelly town. The castle was relieved by a Norman army in September 1403.
The plan of the castle consists of a square inner bailey defended by four round towers, which overlook a semi-circular outer curtain wall on the landward side, with the massive gatehouse next to the river. The river prevents this from being a truly concentric plan, however a jutting tower protects the riverside walls, and the final plan is very strong. The castle is relatively well-preserved, and is managed by Cadw.
The surrounding countryside is reputedly haunted by the headless ghost of Gwenllian ferch Gruffydd, wife of the Welsh prince Gruffydd ap Rhys, who was beheaded in 1136.
Kidwelly was used as a location for the film Monty Python and the Holy Grail, appearing in the very first scene after the titles.
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.
