Lydstep Palace is a ruinous medieval hall house. Believed to have been built in the late 14th century or 15th century, the building was constructed from limestone and built in two levels, the upper floor containing a hall and the lower floor consisting of several barrel vaulted rooms, likely cellars. The two floors were not connected internally, only by external stone stairs. Speculation as to the purpose of the house varies, some sources attribute the building as a court of the Manor of Manorbier and Penally, but it has also been referred to as a hunting lodge of the Bishop Gower of St. Davids.
The house was traditionally known as the Place of Arms, and it is speculated that this became mutated to the Palace of Arms, leading to its current name of the Palace. The building is also referred to as The Old Palace.
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.
