Cessford Castle is a large ruined mid-15th century L-plan castle near the village of Cessford, midway Jedburgh and Kelso. It1 was built around 1450 by Andrew Ker, 1st Earl of Roxburghe. It is possible that the castle incorporates parts of an earlier structure. The fortalice was built on an L-plan, with a main keep with a wing of almost the same magnitude. With up to six storeys, two of which were barrel vaulted, and with walls up to 4 m thick, it was a formidable place of defence. The castle was besieged in 1523 by the Earl of Surrey. The castle was abandoned in 1650.
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.
