Pennard Castle is a ruined castle, near the modern village of Pennard on the Gower Peninsula. The castle was built in the early 12th century as a timber ringwork following the Norman invasion of Wales. The walls were rebuilt in stone by the Braose family at the turn of the 13th and 14th centuries, including a stone gatehouse. Soon afterwards, however, encroaching sand dunes caused the site to be abandoned and it fell into ruin. Restoration work was carried out during the course of the 20th century.
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.
