The castle, or rather a fortified court in Candleston, was founded in the 14th century on the initiative of the Cantilupe family. It could have been built on the site of an earlier building from the 13th century. At the end of the fifteenth century, it was renovated and rebuilt by Mathew Cradock, a constable of castles in Caerphilly and Kenfig, and around 1500 transformations were made in the range of the great hall. Further modifications were carried out in the 17th century, when a new range was added next to the hall building. The lands of the estate in the Middle Ages were covered with sand from nearby dunes and lost their value, but the building remained inhabited until the 19th century. The last person living in the court was Sir John Nichol. When in 1808 he built a new residence, Candleston was sold and used by new owners as a farm. Eventually it was abandoned at the end of the 19th century and fell into disrepair.
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.
