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 Broch of Clickimin is a large and well preserved, though somewhat restored broch near Lerwick. Originally built on an island in Clickimin Loch (now increased in size by silting and drainage), it was approached by a stone causeway. The water-level in the loch was reduced in 1874, leaving the broch high and dry. The broch is situated within a walled enclosure and, unusually for brochs, features a large 'blockhouse' between the opening in the enclosure and the broch itself. Another unusual feature is a stone slab featuring sculptured footprints, located in the causeway which approached the site. Situated across the loch is the Clickimin Leisure Centre.
