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 Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
