Culswick Broch is an unexcavated coastal broch, an Iron Age drystone hollow-walled structure. Built of striking red stone, it has beautiful views all around, including Foula and Vaila isles, and Fitful Head and Fair Isle in the south. The broch stands commandingly on the top of a massive rock platform and is about 3 metres high at its tallest point. Much rubble has fallen into the centre. This broch has a massive triangular lintel stone over the entrance, which is partly filled with rubble.
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.
