Kirchberg Castle was initially built around 1240. The first documented mention in 1265 refers to Raben von Kirchberg. The complex was expanded until 1400. Ludwig Kasimir von Hohenlohe bought the castle back in 1562. Under Kasimir and his sons, extensive changes took place: between 1590 and 1597, the medieval castle was transformed into a Renaissance palace. From this period date the hall building, erected on the site of the first castle, two cross buildings, and connecting passages, creating a four-wing complex with bastions facing the town.
Leopoldo Retti planned the conversion into a residence palace under Count and later Prince Karl August of Hohenlohe-Kirchberg, which took place from 1738 to 1745.
The building complex now includes a café, a hotel with conference rooms, and artist studios.
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.
