Castello di Pollenzo is one of the former residences of Savoy family. In 1997, the castle was placed on the UNESCO World Heritage Site list along with 13 other residences of the House of Savoy.
The castle was originaly built in the Middle Ages, but it was reconstructed to the current appearance between 1832-1848 by Charles Albert of Sardinia.
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.
