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:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
