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:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
