Craignethan Castle is a ruined castle in South Lanarkshire, Scotland. Built in the first half of the 16th century, Craignethan is recognised as an excellent early example of a sophisticated artillery fortification, although its defences were never fully tested.
Craignethan is built on an imposing site above a bend in the River Nethan. Steep slopes protect the castle on the south, north and east sides, but the castle is actually overlooked by higher ground to the west, making it far more vulnerable than it appears. Craignethan's defences are therefore concentrated towards the west. The castle comprises a low central keep, within a rectangular walled courtyard. To the west is a deep ditch and beyond, a larger outer courtyard. The rectangular keep measures 21m by 16m, and was originally of two storeys plus an attic.
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.
