At about 40m long, Carlungie Earth House is one of the largest and most complex examples of its kind in Scotland. It was accidentally discovered during ploughing in 1949. Subsequent excavations during the following two years also revealed about eight associated stone dwellings at ground level.
Earth houses, or souterrains as they are also known, were not dwellings, but stone-lined underground passages which typically date to the Iron Age. They’re found along much of eastern Scotland, as well as in Ireland, Cornwall and Brittany.
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.
