Bonde Palace (Bondeska palatset) is located between the House of Knights (Riddarhuset) and the Chancellery House (Kanslihuset). It is, arguably, the most prominent monument of the era of the Swedish Empire (1611–1718), originally design by Nicodemus Tessin the Elder and Jean De la Vallée in 1662-1667 as the private residence of the Lord High Treasurer Gustaf Bonde (1620–1667) it still bears his name, while it accommodated the Stockholm Court House from the 18th century and since 1949 houses the Swedish Supreme Court.
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.
