A motte-and-bailey castle is thought to have previously occupied the site of Llawhaden Castle and the present structure was built by the bishops of the Diocese of St David in the 13th century. The castle was abandoned in the 16th century and some of the stone was removed for local building projects. The site is privately owned by the Lord of the Manor of Llawhaden and managed by Cadw.
The remaining ruins date from the early 13th century. It is surrounded by a ditch, which was designed to be only crossable by a drawbridge. The castle is pentagonal in shape and while the north-western and western sides of the castle are no longer present, the other three sides remain. The gatehouse is located on the southern side, which is formed of two drum towers and a gateway. This was also where the drawbridge would have been located to allow entrance to the interior of the castle.
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.
